Wireless sensor networks enable long-term environmental monitoring or object tracking through large numbers of unconnected sensor nodes. Because of their large deployment, sensor nodes are expected to be inexpensive to manufacture, small in size, and able operate for many months.
While standard consumer AA or coin-style batteries keep sensor nodes active for up to a year, CAP-XX supercapacitors can work with the battery configuration to extend the life of each node by providing peak power during transmissions as needed while easily conforming to form factor limitations. Supercapacitors are also an excellent power storage solution solar cells, thermoelectrics, and other alternate power solutions for wireless sensor devices.
