Geometry‐Encoded Soft Strain Sensing via Liquid‐Metal Transmission Lines

Advanced Science, EarlyView.
This study presents a liquid‐metal transmission‐line strain sensor that achieves intrinsic decoupling by encoding axial elongation into propagation delay. The time‐domain readout remains stable under complex off‐axis. This enables reliable, repeatable, real‐time elongation measurement in dynamic, multiaxial loading environments for wearable electronics,

Graphene (0002)/Diamond (111) Heterojunction with High Piezoresistive Response. [PDF]

Adv Sci (Weinh)
Graphene/diamond heterostructures show promise as silicon alternatives for semiconductors, but high‐quality integration is challenging. Thermal electron irradiation enables covalent bonding; lonsdaleite acts as an intermediate. The heterostructure exhibits a high piezoresistive response (gauge factor −1149) associated with electron‐rich layers and ...

Drift Reduction in 2D PtSe2 Piezoresistive Pressure Sensors Through an On‐Chip Wheatstone Bridge

Advanced Electronic Materials, EarlyView.
Drift is a major source of error affecting the accuracy and repeatability of sensors. A Wheatstone bridge (WSB) enables high sensitivity, accuracy, and the elimination of common‐mode drift. We apply the WSB concept to highly sensitive piezoresistive pressure sensors made with two‐dimensional layered platinum diselenide transducers.
