WebNov 6, 2024 · The world's first MEMS-based ultrasonic sensor, offered under the Chirp brand, is a truly groundbreaking product that combines a piezoelectric micromachined ultrasonic transducer (PMUT 3), power-efficient DSP (digital signal processor 4), and low-power CMOS ASIC 5 in a small-sized package with size of 3.5 x 3.5 x 1.25 mm. WebThis paper presents flexible piezoelectric micromachined ultrasonic transducers (PMUT) on thin polymer substrate. The flexible PMUT is based on AIN piezoelectric thin film with a new structural configuration optimized for flexibility. The measured resonant frequency, effective coupling coefficient and displacement sensitivity are 2.58 MHz, 1.42% and 30 nm/V, …
