DTS in Germany uses thin film technology for their Low Power Thermoelectric Generators that produce a couple of tens of microwatts within the volt range for a temperature difference of a few levels C. Also in Germany, researchers at Dresden University have found a way to make tiny thermoelectric turbines utilizing copper foil as a template. Antimony-Bismuth thermocouples are electro-deposited and after adding an epoxy film the copper is etched away. The result is a cheap, versatile and recycable generator that converts environmental warmth into electrical energy. The growth by pulsed laser deposition of high-quality thermoelectric cobaltate thin movies on silicon has been reported by Yu et al. .
The future of tech is right here and it’s within the type of a self-cleaning water bottle! Using particular UV-C LED mild the LARQ will clean the waterinside your water bottle and the water bottle itself. You can control it through the app right from your smartphone and by no means have to worry about luke-warm drinks once more.
