Thermoelectric Coated Glass Fiber Motion Sensors
Summary
Researchers at Purdue University have developed a new sensor that uses this phenomenon to detect motion. It works by measuring the voltage with respect to the airflow around it. By filtering the response, it is possible to distinguish ambient air motion from human motion within a small area. This could be used for perimeter intrusion detection systems. While it does not have the sensitivity of other sensors, this design has the advantage of being inexpensive, self-powered, and simple in design.
