ONIO.ZERO MICROCONTROLLER RUNS WITHOUT A BATTERY

ONIO.ZERO MICROCONTROLLER RUNS WITHOUT A BATTERY

It’s becoming quite obvious that traditional batteries are limiting the progress of IoT devices. They are expensive, they contain harmful chemicals and most importantly All-Batteries-Will-Die. Vemund Kval Bakken chief technology officer and co-founder at ONiO say the real problem with the battery approach to IoT comes when you actually consider the battery shelf life as well as the environmental
