Generating power with a thin, flexible thermoelectric film

The No. 1 nuisance with smartphones and smartwatches is that we need to charge them every day. As warm-blooded creatures, however, we generate heat all the time, and that heat can be converted into electricity for some of the electronic gadgetry we carry. Flexible thermoelectric devices, or F-TEDs, can convert thermal energy into electric power. […]

Epidermal electronics attached to the skin via temporary tattoos (e-tattoos) have been around for more than a decade, but they have their limitations, most notably that they don’t function well on curved and/or hairy surfaces. Scientists have now developed special conductive inks that can […]
