摘要：
A medical device includes a device body (14), a first sensor (10) formed on the device body and including a piezoelectric polymer as a sensor element, the piezoelectric polymer configured to receive ultrasonic energy and a first electrical trace (24) connecting to the first sensor and extending along the device body. A dummy sensor (11) is formed on the device body in proximity of the first sensor and includes a dummy sensor element. A second electrical trace (25) connects to the dummy sensor and extends along the device body in a configuration relative to the first electrical trace, wherein a signal event is discriminated between a signal and noise using a response measured on one or more of the first sensor, the dummy sensor or the second electrical trace.
