We caught a tantalising glimpse of the next generation wearable technology at this year’s Bright SCIdea challenge final.
When we look at our FitBits or Apple Watches, we wonder what they could possibly monitor next. We know the fluctuations of our heartbeat, how a few glasses of wine affect our quality of sleep, and the calories burnt during that run in the park. But what’s next?
If the amazing wearable devices pitched by just three of our Bright SCIdea finalists are anything to go by, then we can look forward to not just next generation health monitoring but possible in-situ treatment too.
In recent times, medics have learnt far more about stress and its effect on our health. Indeed, stress was the focus of Happy BioPatch (from Oxford University and Manchester University) technology. The second place team has incorporated an IP-protected enzyme within a patch that measures your stress levels (by detecting the levels of cortisol in your sweat) throughout the day.
This information migrates from body to phone and notifies you if your stress levels are too high. One of many exciting aspects of this technology is that it could be used by physicians to check if patients need treatment for depression and prevent the serious consequences of stress. As one of the judges said, ‘I like it because it’s preventative.’
From mental health to physical health, two of the other finalists use wearable devices to address maladies in in-situ. BioTech Inov, from the University of Coimbra in Portugal, has developed plans for a subcutaneous biomedical device that tracks the blood sugar levels in diabetes patients. This technology would enable the wearer to track their blood sugar levels and let them know if trouble is lurking.

Another intriguing development was the in-device treatment developed by the Hatton Cross team (comprising students from the University of Warwick, Imperial College London and Queen Mary University of London). The team is developing wearable technology that can detect wrist pain from sport, or the types of repetitive stress injuries arising from typing or writing too much.
One of the most fascinating aspects of the technology is the potential for in-device treatment. On the preventative side, the device could use vibration to alert users that their wrists are under strain. They also mentioned using heat from the device, or the release of a 0.05 Tesla magnetic field, to relax the muscles.
Another really insightful comment on the technology came from one of the judges. Dr Sarah Skerratt suggested that this type of technology - which is subtly attuned to the movements of the hand and wrist - could theoretically be used in the early diagnosis of Parkinson’s disease or Alzheimer’s disease. That is not to say there aren’t regulatory issues with developing wearable technologies for medical purposes, as the judges pointed out, but the potential of such devices is huge.

The staggering thing is that the technologies pitched by the Bright SCIdea finalists are just three of the myriad innovations being developed around the world at the moment.
Thirty years ago, few of us could have imagined that we would have a personal computer, music system, TV, watch, video, phone, camera, and games console all encapsulated within a single box that fits in our pockets. In 30 years’ time, we will scarcely be able to believe the health capabilities of the devices worn on our wrists and bodies.
Perhaps you will have heard of them first during the Bright SCIdea challenge?
Which technologies will propel industry forward and give companies that competitive advantage? According to digital consultancy McKinsey Digital’s Tech Trends Index, several technologies will have a profound and disruptive impact on industries including the chemical sector. So, which ones will have the biggest effect on the way you work in the coming decade?
By 2025, more than 50 billion devices around the world will be connected to the Industrial Internet of Things (IIOT) and about 600,000 industrial robots a year will be in place from 2022. The combination of these, along with industrial processes such as 3D and 4D printing, will speed up processing and improve operational efficiency.
According to McKinsey, 50% of today’s work practices could be automated by 2022 as ever more intelligent robots (in physical and software form) increase production and reduce lead times. So, how does this change look in the real world?
According to the McKinsey Tech Trends Index, 10% of today’s manufacturing processes will be replaced by additive manufacturing by 2030.
According to the Tech Trends Index, one large manufacturer has used collaborative robots mounted on automatic guided vehicles to load pallets without human involvement, while an automotive manufacturer has used IIOT to connect 122 factories and 500 warehouses around the world to optimise manufacturing and logistics, consolidate real-time data, and boost machine learning throughput.
An almost incredible 368,000 patents were granted in next generation computing in 2020. Advanced computing will speed up the processing of reams of data to optimise research and cut development times for those in the chemicals and pharmaceuticals industries, accelerate the use of autonomous vehicles, and reduce the barriers to industry for many eager entrants.
‘Next-generation computing enables further democratisation of AI-driven services, radically fast development cycles, and lower barriers of entry across industries,’ the index notes. ‘It promises to disrupt parts of the value chain and reshape the skills needed (such as automated trading replacing traders and chemical simulations, reducing the need for experiments).’
According to McKinsey, AI will also be applied to molecule-level simulation to reduce the empirical expertise and testing needed. This could disrupt the materials, chemicals, and pharmaceuticals industries and lead to highly personalised products, especially in medicine.
It doesn’t take much investigation before you realise that the bio-revolution has already begun. Targeted drug delivery and smart watches that analyse your sweat are just two ways we’re seeing significant change.
The Tech Trends Index claims the confluence of biological science and the rapid development of AI and automation are giving rise to a revolution that will lead to significant change in agriculture, health, energy and other industries.
In the health industry, it seems we are entering the age of hyper-personalisation. The Index notes that: ‘New markets may emerge, such as genetics-based recommendations for nutrition, even as rapid innovation in DNA sequencing leads ever further into hyper personalised medicine.’ One example of this at work in the agri-food industry is Trace Genomics’ profiling of soil microbiomes to interpret health and disease-risk indicators in farming.
It’s no secret that we will need to develop lighter materials for transport, and others that have a lighter footprint on our planet. According to McKinsey, next generation materials will enhance the performance of products in pharma, energy, transportation, health, and manufacturing.
For example, molybdenum disulfide nanoparticles are being used in flexible electronics, and graphene is driving the development of 2D semiconductors. Computational materials science is another area of extraordinary potential. McKinsey explains: ‘More new materials are on the way as computational-materials science combines computing power and associated machine-learning methods and applies them to materials-related problems and opportunities.’
5G networks will help take autonomous vehicles from tentative - to widespread use.
So, which sorts of advanced materials are we talking about? These include nanomaterials that enable more efficient energy storage, lighter materials for the aerospace industry, and biodegradable nanoparticles as drug carriers within the human body.
These are just four of the 10 areas explored in the fascinating McKinsey Digital’s Tech Trends report. To read more about the rest, visit: https://www.mckinsey.com/business-functions/mckinsey-digital/our-insights/the-top-trends-in-tech
We are increasingly conscious of the need to recycle waste products, but it is never quite so easy as rinsing and sorting your waste into the appropriate bins, especially when it comes to plastic.
Despite our best intentions, only around 16% of plastic is recycled into new products — and, worse, plastics tend to be recycled into low quality materials because transformation into high-value chemicals requires substantial amounts of energy, meaning the choices are either downcycling or prohibitively difficult. The majority of single-use plastics end up in landfills or abandoned in the environment.
This is a particular problem when it comes to polyolefins such as polyethylene (PE) and polypropylene (PP), which use cheap and readily available raw materials. Approximately 380 million tonnes of plastics are generated annually around the world and it is estimated that, by 2050, that figure will be 1.1 billion tonnes. Currently, 57% of this total are polyolefins.
Why are polyolefins an issue? The strong sp3 carbon–carbon bonds (essentially long, straight chains of carbon and hydrogen atoms) that make them useful as a material also make them particularly difficult to degrade and reuse without intensive, high energy procedures or strong chemicals. More than most plastics, downcycling or landfill disposal tend to be the main end-of-life options for polyolefins.
Polyethylene is used to make plastic bags and packaging.
Now, however, a team of scientists from MIT, led by Yuriy Román-Leshkov, believe they may have made a significant step towards solving this problem.
Previous research has demonstrated that noble metals, such as zirconium, platinum, and ruthenium can help split apart short, simple hydrocarbon chains as well as more complicated, but plant-based lignin molecules, in processes with much lower temperatures and energy.
So the team looked at using the same approach for the long hydrocarbon chains in polyolefins, aiming to disintegrate the plastics into usable chemicals and natural gas. It worked.
First, they used ruthenium-carbon nanoparticles to convert more than 90% of the hydrocarbons into shorter compounds at 200 Celsius (previously, temperatures of 430–760 Celsius were required).
Next, they tested their new method on commercially available, more complex polyolefins without pre-treatment (an energy intensive requirement). Not only were the samples completely broken down into gaseous and liquid products, the end product could be selected by tuning the reaction, yielding either natural gas or a combination of natural gas and liquid alkanes (both highly desirable) as preferred.
Polypropylene is used in bottle caps, houseware, and other packaging and consumer products.
The researchers believe that an industrial scale use of their method could eventually help reduce the volume of post-consumer waste in landfills by recycling plastics to desirable, highly valuable alkanes — but, of course, it's not that simple. The team says that more research into the effects of moisture and contaminants in the process is required, as well as product removal strategies to decrease the formation of light alkanes which will be critical for the industrialisation of this reaction.
However, they believe the path they're on could lead to affordable upcycling technology that would better integrate polyolefins into the global economy and incentivise the removal of waste plastics from landfill and the environment.

The Organisation for Economic Cooperation and Development (OECD) has published its Science Technology and Innovation Outlook 2021: Time of Crises and Opportunity report.
Published at the beginning of 2021, the report focuses on the ‘unparalleled mobilisation of the scientific and innovation community’ in response to the covid-19 pandemic. The report indicates that newly funded research initiatives have been established by public research agencies and organisations, private foundations and charities, while the health sector has similarly invested in an array of research programmes worth billions of dollars in record time.

However, the report also exposes gaps in overall system resilience to future crises. ‘It’s a wake-up call that highlights the need to recalibrate science, technology and innovation (STI) policies, so that they better orient research and innovation efforts towards sustainability, inclusivity and resiliency goals,’ the report asserts.
Highlighting the rapid response by governments around the world, the report indicates that in the first few months of the pandemic, national research funding bodies spent around $5 billion on emergency financial support. This includes $300 million in Asia-Pacific, excluding China, over $850 million in Europe and more than $3.5 billion in North America. At the same time, research efforts led to around 75,000 scientific publications on covid-19 being released between January and November 2020, the report says. The largest share came from the US, followed by China and the UK. Research databases and scientific publishers removed paywalls so that covid-19 related information could be quickly shared.

‘These developments mark important changes that could accelerate the transition to a more open science in the longer run,’ the report says. It is also noted that not only have researchers continued their work with more than three quarters of scientists indicating that they had shifted to working from home at some point in 2020, but almost two thirds experienced, or expected to see, an increase in the use of digital tools for research as a consequence of the crisis. The report also mentions the contribution of the general public, with so called ‘frugal innovations’ in response to shortages of medical equipment and emergency supplies.
Looking to the future of the research community, the report says that postgraduate training regimes require reform to support a diversity of career paths. ‘The crisis has shown that the need for STI expertise is not limited to the public laboratory; it is also important for business, government and NGOs […] Reforming PhD and post-doctoral training to support a diversity of career paths is essential for improving societies’ ability to react to crises like covid-19 and to deal with long-term challenges like climate change that demand science-based responses […] There has been a 25% increase in the number of people with PhDs in OECD countries over the past decade with no corresponding increase in academic posts. The pandemic is expected to make matters worse, more than half of the scientists participating in the OECD Science Flash Survey expect the crisis to negatively affect their job security and career opportunities,’ the report says.

While still in the midst of the pandemic, the report stresses that STI policies now need to be reoriented to tackle the challenges of sustainability, inclusivity and resiliency. ‘In the short-term governments should continue their support for science and innovation activities that aim to develop solutions to the pandemic and mitigate its negative impacts, while paying attention to its uneven distributional effects. Science for policy will remain in the spotlight as governments seek to strike the right balance in their response to covid-19. This will effect public perceptions of science that could have long term implications for science-society relations.’
The report concludes that governments now have the task of developing public sector capabilities to deliver more ambitious STI policy. This will require engagement from stakeholders and citizens in order to capture a diversity of knowledge and values.
