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

open access: yesAdvanced 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 ...

Passive Shape‐Adaptive Fluidic Interface for Enhanced Skin‐Sensor Coupling in Wearable Devices

open access: yesAdvanced Materials Technologies, EarlyView.
This study presents a passive fluidic interface for wearable biosensors that adapts to static and dynamic body shape changes to maintain consistent skin contact. Flexible, fluid‐filled pouches redistribute pressure from high‐load areas to regions requiring improved contact, enhancing signal quality and comfort in a compact, low‐energy design for ...

Optofluidic Raman Analysis and Capacity Recovery in Li‐ion Cells

open access: yesAdvanced Materials Technologies, EarlyView.
Operando Raman spectroscopy is used to monitor the degradation of commercial Li‐ion cells. Using a microfluidic access port, small amounts of electrolyte are sampled into a hollow‐core optical fibre, where fibre‐enhanced Raman analysis reveals Li+ solvation changes and solvent evolution.

Graphene‐Based Wearable Textile Triboelectric Nanogenerators and Biomechanical Sensors

open access: yesAdvanced Materials Technologies, EarlyView.
This study presents a wearable textile‐based triboelectric nanogenerator (T‐TENG) using sprayed graphene enhanced with a PVA adhesion layer. The graphene‐based electrode demonstrates high electrical conductivity and robustness to multiple bends. The fabricated T‐TENG provides stable and efficient output, with strong responsiveness to biomotion.
