Description

This talk will cover wireless sensor node and low-cost wearable wireless sensing technology for gas detection. Sensor designs use electromagnetic waves for detection, involving microwaves and optical technology. Sensor heads are fabricated using nanotechnology. Full prototype integration, sensor head design and results will be described. Microwave sensor design and implementation for dielectric material identification will also be covered.
