Development of PMUT Array Packaging from Characterisation Prototypes to Customer Samples

PMUT (Piezoelectric Micromachined Ultrasonic Transducers) can be used in a wide number of medical and industrial applications, from high-end ultrasound scanning which requires a large array of membranes and interconnects to the ASIC driver/receiver, to therapeutic ultrasound and energy delivery which require a small number of membranes/interconnects. Different packaging needs have been required during the development program for the characterisation of the PMUT devices and the requirements of...

An Ultrasonically Powered System Using an AlN PMUT Receiver for Delivering Instantaneous mW-Range DC Power to Biomedical Implants

Aluminum Nitride (AlN) Piezoelectric Micromachined Ultrasonic Transducers (PMUTs) are gaining interest for biomedical implant power due to biocompatibility and low-temperature processing. However, due to the low piezoelectric coefficient of AlN PMUTs, storage capacitors are often used to accumulate ultrasonic power transferred over an extended time. The accumulated energy is then used to power a DC load, which leads to a long start-up time, and insufficient duty cycle for some applications. W...

A Comparative Study of Si3N4 and Al2O3 as Dielectric Materials for Pre-Charged Collapse-Mode CMUTs

Capacitive Micromachined Ultrasound Transducers (CMUTs) have many advantages compared to other ultrasonic transducer technologies, especially for implantable devices. However, they require a high bias voltage for efficient operation. To eliminate the need for an external bias voltage, a charge storage layer can be embedded in the dielectric. This study aims to compare the performance of Si3N4 and Al2O3 when used as a charge storage layer. By measuring the shift in the C-V curve, Si3N4 exhibit...
