Self-Powered Batteries for IoT
À̹®Çü °­³²Æ÷½ºÆ® Çлý±âÀÚ | ½ÂÀÎ 2021.06.07 21:28

The number of devices connected to the internet, commonly called the internet of things (IoT), has increased dramatically since 2012 with the number going beyond 10 billion in 2020.10 billion devices require incredible amounts of power, mostly in the form of batteries, and with the number of IoT to continue to increase, sustaining that much will become an energy crisis.

Ben Calhoun and Dave Wentzloff, after completing their doctorates at MIT and continuing their work at their undergraduate alma maters, came together to found Everactive in 2012. Everactive aims to solve problems of getting rid of the battery and finding a new low-power wireless network with their ultra-low-power integrated circuits.

Calhoun’s research concentrated on low-power digital systems, while Wentzloff’s research explored low-power communication. Their product is the Eversensors, which utilizes ultra-low-power circuits and wireless communication. These sensors are self-sustaining, harvesting energy from their surroundings. These show much more potential than regular batteries in terms of scalability and cost less to operate.

Everactive first started working with the industrial field, specifically steam traps, but they hope to widen their area. Wearable consumer products and logistics are next on Everactive’s list. And, in the coronavirus situation, Everactive expects to play a great part in promoting self-powered systems and ubiquitous remote monitoring.
