In October, Horizon discovers a futuristic world of transparent e-books, plastic solar cells and electronic skin with a look at some of the applications of organic electronics. We speak to organic chemist Prof. Andreas Hirsch about how using carbon rather than silicon in electronics can make them flexible, lightweight and biocompatible and could lead to a new generation of human-looking robots and ‘chemical’ computing. We take a look at work to create electronic skin – self-healing, stretchable material that can mimic some of the functions of human skin – and its potential uses. We discover how thin, flexible, plastic solar cells could turn surfaces such as cars and fabric into sources of renewable energy, and we uncover some novel approaches to charging wearable electronics.
Picture this: You’ve experienced no physical sensation beyond your wrists for years, then a doctor drapes a thin, flexible membrane over your hand and, like magic, you can feel the trickle of water through your fingers again.
Thanks to rapid computing developments in the last decade and the miniaturisation of electronic components, people can, for example, track their movements and monitor their health in real time by wearing tiny computers. Researchers are now looking at how best to power these devices by turning to the user’s own body heat and working with garments, polka dots and know-how from the textile industry.
Today’s silicon solar panels are an industry standard, but these rigid, heavy blocks may be shunted aside by plastic rivals – lightweight, flexible solar panels that could be printed and stuck onto buildings or placed in windows or cars, turning light into electricity in locations inaccessible to their heavier cousins.
Electronics made from carbon rather than silicon could lead to a new generation of medical devices, sensors and perhaps even robots, according to Professor Andreas Hirsch, chair of organic chemistry at Friedrich-Alexander-University Erlangen-Nürnberg in Germany.
The asteroids in our solar system are the remnants of planetary formation. They hold clues about how the Milky Way formed, but they also hold promise and peril for humans as the source of both rich materials and potentially dangerous cratering events. This month we look at the latest in asteroid research. We speak to Dr Naomi Murdoch, a planetary scientist, about her work investigating asteroids, how to land on them and how to defend Earth from a dangerous event. We look in depth at how scientists in the field of planetary defence are developing rapid response techniques to detect an Earth-bound ‘imminent impactor’, determine within days whether it’s dangerous, and evacuate people from the danger zone. We speak to scientists studying exactly what asteroids are composed of so that we can categorise them from Earth, and we look at work studying asteroid dust to see what it can tell us about the early days of our solar system and the origins of life on our planet.
With around half a million species of insects reported to be at risk of extinction and studies already showing a large decline in abundance, this month Horizon looks at what reduced insect biodiversity means for us – and what we can do about it. We speak to rove beetle expert Dr Alexey Solodovnikov about the services insects provide, from waste disposal and pollination to monitoring climate change and providing information about a new pandemic. We find out how scientists hope to cut the use of pesticides – one of the big culprits for reducing insect diversity – with new ways of pest control. We look at how efforts to boost urban green space in Europe’s cities is impacting insect life and we ask whether people’s attitudes to insects affect conservation efforts.
The hyperloop is what you get when you take a magnetic levitation train and put it into an airless tube. The lack of resistance allows the train, in theory, to achieve unseen speeds, a concept that is edging closer and closer to reality – and could provide a greener alternative to short-haul air travel.
Picture yourself speeding down the highway with no hands on the wheel, checking your emails while your car takes care of responding to what’s happening on the road. Would you trust your car to make the right decisions? If you have doubts, you’re not alone.
Hyperloops could replace short-haul air travel.
Car manufacturers are rolling out higher levels of automation but public acceptance is lagging behind.
