An Ultra‐Reliable and Highly Sensitive Flexible Piezoelectric Pressure Sensor Based on Vertically Aligned Gallium Nitride Microrod Arrays on Graphene

Advanced Materials Interfaces, EarlyView.
A flexible and highly reliable piezoelectric pressure sensor based on GaN p–n homojunction microrod arrays on graphene is demonstrated. The sensor exhibits high sensitivity, rapid response, excellent cyclic durability, and stable performance after thermal aging and PBS immersion, highlighting its potential for harsh‐environment and biomedical pressure ...

Transducers Across Scales and Frequencies: A System‐Level Framework for Multiphysics Integration and Co‐Design

Advanced Materials Technologies, EarlyView.
Transducers convert physical signals into electrical and optical representations, yet each mechanism is bounded by intrinsic trade‐offs across bandwidth, sensitivity, speed, and energy. This review maps transduction mechanisms across physical scale and frequency, showing how heterogeneous integration and multiphysics co‐design transform isolated ...
