Objective:
Self powered sensor networks with
focus on industrial health monitoring, aircraft structural
health monitoring, perimeter security nets and border
intrusion monitoring. Goal is to reach the power density
of 2mW/cm².
Approach:

Accomplishments:
Build several prototypes to harvest
the vibration and wind energy. Pictures below show the
prototypes of the piezoelectric windmill and vibration
generator. Our current work includes the design of energy
harvesting chips, consisting of 3D layers containing
multiple types of energy capturing technologies.

The prototyping of a multi-energy input,
3D harvester is in progress.
