A sub-microwatt self-powered fatigue sensor

SPIE Proceedings, 2007
Fatigue and overload of mechanical, civil and aerospace structures remains a major problem that can lead to costly repair and catastrophic failure. Long term monitoring of mechanical loading for these structures could reduce maintenance cost, improve longevity and enhance safety.

Feasibility study of a self-powered piezoelectric sensor

SPIE Proceedings, 2004
Sensors play a crucial role in structural systems with the concern of reliability/failure issues. The development of wireless monitoring systems has been of great interest because wireless transmission has been proven as a convenient means to transmit signals while minimizing the use of many long wires.

Passive (self-powered) fiber optic sensors

IEEE Conference on Nuclear Science Symposium and Medical Imaging, 2003
Oak Ridge National Laboratory is developing a new group of fiber-optic sensors for characterizing physical aspects such as ambient temperature. These sensors exploit the inherent property of thermographic materials that the lifetime and/or intensity of the emitted fluorescence decreases with increasing temperature.
