Partnership Yields Battery-Free Wireless Sensors

BRIDG has collaborated with Face International Corporation to develop the Evercell power cell, a patented energy-harvesting technology that’s capable of powering wireless IoT sensors without batteries. Evercell technology employs a unique design and advanced materials to harvest thermal energy in any environment where the ambient temperature is above absolute zero.

 

Reportedly, the power cells are inexpensive to produce. They consume no fuel, have no moving parts, and contain no toxic materials. According to company officials, an Evercell demonstration device has been operating continuously for 16 months with undiminished performance, producing enough electrical output to power a typical wireless sensor.

The breakthrough energy harvesting power cell was developed and patented by Face International Corporation. As part of the collaboration to commercialize the technology, BRIDG and Face intend to cooperatively undertake technology validation for product integration development and prototype manufacturing of power cells at its NeoCity campus in central Florida, with the goal to achieve mass production by 2019, based on customer-driven demand.

 

Evercell technology in a nutshell:

  • Delivers continuous power output without requiring a perceptible temperature differential (in essentially any environment above absolute zero)
  • Utilizes existing semiconductor manufacturing processes
  • Solid state structure
  • No toxic materials
  • Scalable output – can be made in various form factors
