N2 - In this paper we describe an implementation of a novel fatigue monitoring sensor based on integration of piezoelectric transduction with floating gate avalanche injection. The miniaturized sensor enables continuous batteryless monitoring and time-to-failure predictions of biomechanical implants. Measured results from a fabricated prototype in a 0-5μm CMOS process indicate that the device can compute cumulative statistics of electrical signals generated by piezoelectric transducer, while consuming less that 1μW of power. The ultra-low power operation makes the sensor attractive for integration with poly-vinylidene diflouride (PVDF) based transducers that have already proven to be biocompatible.
