|Abstract(s):||The miniaturization of parts is an essential step in the evolution of technology, where more functions are integrated in less space. Therefore in recent years there is a growing interest in microsystems due to the number of possible applications in several different areas. This paper describes a different approach to the production of one of these devices, a piezoresistive accelerometer. The main structure of the proposed accelerometer is made of thermoplastic material and consists of a proof mass connected to an external structure by four arms. At the end of each arm, transduction a pizoresisistive material is used for transduction. . Resorting to a Wheatstone bridge and an amplifier the accelerometer output is successfully acquired, proving that this geometry and principle works.|
