Abstract
A reliable two-channel data telemetry system with remote RF powering capability is developed for high-performance industrial wireless MEMS strain sensing applications. The prototype system is insensitive to mechanical rotation and can simultaneously transmit and receive digital Manchester-coded sensors data at 2.5 Mbps and 50 kbps by employing phase shift keying (PSK) and load shift keying (LSK) modulation schemes, respectively, over the same wireless link used for remotely RF powering the strain sensing microsystem. The remote RF powering system can produce a stable DC voltage of 2.8 V with a 2 mA of current supply capability from a 50 MHz RF operation. The demonstrated performance is adequate for realizing a wireless strain sensing microsystem providing a high resolution (high data rate) strain information together with a low data rate temperature information for real-time calibration and intelligent system control
