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 ...

Unraveling and Mitigating Resolution Loss in UV‐Assisted Vapor Phase Polymerization of Monolithic PEDOT:Tosylate Electrochromic Patterns

Advanced Optical Materials, EarlyView.
This work aims to understand the origin of pattern deviation in PEDOT:Tos films formed via vapor phase polymerization on UV‐exposed oxidant. UV exposure induces formation of loosely bound water which diffuses and produces macroscopic structuring at increased block copolymer contents.
