Electronics for LabView Based Piezoresistive Microcantilever Sensor System

We have developed a simple, low-cost electronic interface suitable for use with piezoresistive microcantilever-based sensors. This interface uses the USB bus of any computer or laptop to communicate with the sensor via SPI commands. The primary user interface is LabView. We have used this system with several "embedded" piezoresistive microcantilever sensing applications, including both liquid-phase and gas-phase sensing.
