AbstractNot Available We propose to monitor temperature and other environmental parameters remotely without hard wire connection or local stored-energy power sources at the sensor. The discrete sensor is a monolithic silicon chip containing capacitive diaphragm structures which monitor temperature barometric pressure, and excessive shock loads. Further development may permit monitoring of humidity with this system. The basic sensing system with a MEMS integrated sensor chip has been presented and reviewed at the 1995 International Conference on Sensors and Transducers in Stockholm. It is also covered by US patent #5,610,340 Integrated (Pressure) Sensor with Remote Power Source and Remote Readout issued March 11, 1997 with co-inventors W. N. Carr and S. Chamarti. The sensor utilizes a resonant LC tank circuit which determines the barrier frequency of the chip oscillator in addition to serving us non-inductive pickup loop for powering the sensor. The sensor utilizes a unique (patented) data communicating device/system embedded in a silicon chip of size typically 0.5x2.0x2.0 millimeters. , The sensor will be extremely environmentally stable. The silicon chip melts at 1412C. Residual films on the silicon are oxides and thin aluminum typically less then 1 micron thickness. Remote interrogation/power devices will store sensor readout data. BENEFITS: The remote sensing system to be demonstrated under this SBIR will have general applicability for close-proximity parameters testing using disposabl
