Wear your smartwatch, or smart band without charging, using a new innovation where devices can charge themselves using human sweat
Your perspiration generates long-term, continuous power thanks to microbial biofilm A microbial biofilm has been proven as a cohesive, flexible material that absorbs evaporation energy and converts it to electricity by researchers at the University of Massachusetts Amherst. This biofilm has the potential to change the face of wearable electronics by powering everything from personal medical sensors to personal gadgets. The biofilm is a thin layer of bacterial cells the thickness of a sheet of paper. It is made naturally by a genetically modified strain of the bacterium Geobacter sulfurreducens. This microorganism is known to create energy and has previously been used to power electrical equipment in "microbial batteries." However, such batteries need the right care and feeding of G. sulfurreducens. In contrast, because it is dead, the new biofilm, which can give as much energy as a comparable sized battery, functions continually. It also doesn't need to be fed because it...
