Trimmable links for selectively setting transducer impedance

Abstract

Systems and methods are disclosed herein for selectively configuring an impedance of a transducer. A configurable transducer system is provided that can include a first region configured for receiving an applied stress and one or more sensing branches in communication with the first region. Each sensing branch can include an active piezoresistive area; three or more conduction paths configured in electrical communication with the active piezoresistive area; one or more trimmable links configured in parallel communication with at least two of the three or more conduction paths; and two or more connection terminals in electrical communication with the three or more conduction paths. The trimmable links are configured to be selectively opened to set a value of nominal impedance associated with the active piezoresistive area based on a desired impedance of the configurable transducer.
