Nanopower Electronics Provide Wireless Links Without Using Batteries

One part of wireless technology that is currently in a rapid growth phase is ultra-low power. Sensors and the wireless transmission of their data offers many valuable possibilities in the monitoring and control of building HVAC systems, gathering meteorological and climate data, providing real-time measurement of stress-es on the structure of aircraft, and many other applica-tions. This report presents a number of new developments in the area, from ZigBee and IEEE802.15.4 wireless, to devices that harvest energy from the environment to power those devices with no need for batteries.
