Tiny solar-powered sensor runs 'almost forever'
Boffins have created the world's smallest solar-powered sensor which can harvest energy from its surroundings to operate nearly perpetually.Inside the tiny 25.mmX3.5mmX1mm device are solar cells, a battery and a processor. This makes it 1,000 times smaller than comparable commercial counterparts.
Makers at the University of Michigan say the device could enable new biomedical implants because its average power consumption is less than 1 nanowatt.
All we know is that given its size you would have to be careful where you put it… no, not the most insightful scientific analysis was it?
"Our system can run nearly perpetually if periodically exposed to reasonable lighting conditions, even indoors," said David Blaauw, an electrical and computer engineering professor.
"Its only limiting factor is battery wear-out, but the battery would last many years."
