Fiber‐Based Wearable Electronics as Adaptive Biointerfaces for Healthcare Applications

Advanced Functional Materials, EarlyView.
Fiber‐based wearable electronics have been extensively studied as adaptive healthcare biointerfaces. In this review, we classify and introduce fiber‐based systems according to biointerface design, conductive materials, transduction mechanisms, and healthcare applications, and provide a perspective on their translation toward reliable, continuous ...

Validation and evaluation of a low-cost fabric-based tactile sensor in comparison with an sEMG sensor

e-Prime: Advances in Electrical Engineering, Electronics and Energy
Tactile sensors play an increasingly crucial role in the monitoring of muscle behaviour during diverse activities. Regrettably, accessibility is restricted by the high cost of commercial Electromyography (EMG) systems.

GelSight: High-Resolution Robot Tactile Sensors for Estimating Geometry and Force

Sensors, 2017
Tactile sensing is an important perception mode for robots, but the existing tactile technologies have multiple limitations. What kind of tactile information robots need, and how to use the information, remain open questions.

3D‐Printed Gradient Shape‐Memory Strain Sensors With Rewritable Gauge Factors

Advanced Functional Materials, EarlyView.
A 3D‐printed shape‐memory strain sensor combines thermomechanical programming with gradient architectural design. Preset strain rewrites the gauge factor (GF), while the gradient geometry amplifies the response through strain redistribution. Reprogrammable sensitivity enables the same sensor to detect weak pulse signals and monitor large‐amplitude ...
