Abstract:
1. A miniature pressure scanning system comprising: a plurality of miniature pressure sensors including a plurality of sensor outputs, each of the miniature pressure sensors including at least one sensor output for providing an analog output signal indicative of a detected pressure on a body, and each at least one sensor output having an associated output impedance; a plurality of buffers, each buffer electrically connected to the sensor output of a corresponding one of said miniature pressure sensors, and configured to reduce the associated output impedance of the corresponding miniature pressure sensor output coupled thereto, and further configured to provide at an output of said buffer the analog output pressure signal from the miniature pressure sensor; and a multiplexer coupled downstream of the plurality of buffers and configured to multiplex the buffered analog output pressure signals to output a multiplexed analog signal representing the detected pressures.
