Industrial and Social Applications of Wireless Sensor Nets with “Energy Scavenging”
With a case study on “battery-less” tiny-temperature nodes for “smart building applications”

Energy Scavenging
GOAL: Design an ‘infinite life’ power source for a sensor node
APPLICATION: Wireless Sensor Networks in Buildings
VISION: Millions of self-powered sensor/transceivers, each the size of a speck of dust, will infiltrate a building and create a smart environment
PROOF OF CONCEPT: To power a Mica2Dot Mote using vibrations from a wooden stairway in the Naval Architecture Building
