The high voltage output makes it possible to drive the electroluminescent layer. applied on the Piezo material, different voltage readings corresponding to the force is displayed. I am using the following circuit: The problem is that on top of the sensed data, there seems to exist a low frequency envelope oscillation of period of about 10 seconds. If you have experience with charge amplifiers and piezoelectric sensors and would like to share some advice, feel free to post a message in the comments section below. That means they're plastic and the connection tab is crimped on somewhat delicate material. the cathodes of all the diodes are connected together, and all the ground legs of the bridge rectifiers are connected. Piezo sensor taped to finger Analog values from a piezoelectric sensor taped to my finger. The included Piezo sensor easily mounts to any flat surface for detecting vibration. The DT series sensors are the simplest form of piezo film sensors, used primarily as dynamic strain gages and contact microphones for vibration or impact detection. Position noise is specified as RMS noise measured at the high voltage output to the piezo actuators while the system is in closed-loop.
