A Multimodal Piezoelectric Vertical Sidewall Architecture for Scalable In‐Plane NEMS Resonators

Advanced Electronic Materials, EarlyView.
A vertical in‐plane piezoelectric resonator design shifts frequency tuning from film thickness to lithographic lateral definition, facilitating monolithic multiband integration. Initially validated via microscale length‐extensional resonators, this cavities‐first fabrication approach scales to the nanoscale for high‐frequency operation.

2-D Scanning LiDAR with MEMS Mirror and STM32

IOP Conference Series: Materials Science and Engineering, 2019
Abstract In this paper, the 2-D scanning rangefinding LiDAR based on MEMS mirror and STM32 is proposed, in terms of time-of-flight(TOF) measurement, employing a APD as photodetector in order to steer nanosecond pulsed beam. The aim, centimeter-level measurement accuracy with low power consumption and a scanning angle of $+/-30^\circ ...
