Energy Harvesting Wooden Floors
Researchers from Switzerland are tapping into an unexpected energy source right under our feet: wooden floorings. Their nanogenerator enables wood to generate energy from our footfalls. They also improved the wood used in the their nanogenerator with a combination of a silicone coating and embedded nanocrystals, resulting in a device that was 80 times more efficient—enough to power LED lightbulbs and small electronics.

The Biodegradable Battery
The number of data-transmitting microdevices, for instance in packaging and transport logistics, will increase sharply in the coming years. All these devices need energy, but the amount of batteries would have a major impact on the environment. Researchers have developed a biodegradable mini-capacitor that can solve the problem. It consists of carbon, cellulose, glycerin and table salt. And it works reliably.

Invisible "Keyhole" Made of Printed, Transparent Electronics
What initially looks like a simple transparent film conceals a whole new level of security. Invisible buttons are printed with conductive ink on the transparent carrier material, the position of which is known only to insiders. Such circuits can be connected to a door lock as an access code, for instance. If the buttons on the polymer film are pressed in the correct order, the door opens.

Energy Harvesting Smart Floors
Researchers have made wood compressible and turned it into a micro-generator. When it is loaded, an electrical voltage is generated. In this way, the wood can serve as a bio-sensor - or generate usable energy. The latest highlight: To ensure that the process does not require aggressive chemicals, naturally occurring wood-degrading fungi take over the task of modifying the wood.

Turning Streetwear Into Solar Power Plants
Researchers have succeeded in developing a material that works like a luminescent solar concentrator and can even be applied to textiles. This opens up numerous possibilities for producing energy directly where it is needed, i.e. in the use of everyday electronics.

Transparent Conductive Films and Materials: Transition from old to new
The market composition of transparent conductive films and materials has not dramatically shifted for some years. It is heavily reliant upon select markets such as flat consumer small/medium sized electronic touch screens. Indeed, the IDTechEx Research report Transparent Conductive Films and Materials 2018-2028: Forecasts, Technologies, Players puts this reliance around 85-90% today. The emergence of new applications has also been slower than many had predicted and hoped. This report finds that so-called 'old' applications are still the vast majority of the market.
