Wireless and Self‐Powered Wearable Pressure Sensors Based on Chitosan for Artificial Mechanoreceptors

Advanced Materials Technologies, EarlyView.
A novel self‐powered wearable pressure sensor is fabricated using chitosan‐ZnO composite piezoelectric film, achieving sensitivities of 70.71 mV/kPa and 471.43 mV Hz−1. This lightweight and biodegradable device emulates mechanoreceptors for applications such as object classification, wireless data transmission, and gesture recognition, offering an eco ...

Tough and Fast Thermoresponsive Hydrogel Soft Actuators

Advanced Materials Technologies, EarlyView.
This work develops tough, fast‐responding thermoresponsive double‐network hydrogels that combine excellent mechanical strength with rapid actuation. Composed of PNIPAm and ether‐based polyurethane, the hydrogels achieve ≈8 MPa compressive stress and ≈30% contractile stroke within 2 min at 50 °C, enabling temperature‐responsive fluid flow switching for ...

Vertical Membrane‐Free Organ‐on‐a‐Chip for High‐Throughput In Vitro Studies and Drug Screening

Advanced Materials Technologies, EarlyView.
This novel microfluidic organ‐on‐a‐chip (OoC) platform enables cost‐effective, high‐throughput in vitro modeling. With vertical compartmentalization and gravity‐driven flow, it eliminates porous membranes and external pumps. Successfully generating intestine, cartilage, and tendon models, this study demonstrates drug responses, including 5‐fluorouracil

Advancing Solar Modulation Ability of Near Infrared Thermochromic Cholesteric Liquid Crystal Smart Window Films Using a Waveplate

Advanced Optical Materials, EarlyView.
This work presents the use of a waveplate in thermochromic materials for smart windows. The waveplate enables the optical material to transition from a narrow band reflection to broad band ambidextrous reflection upon heating, resulting in a solar transmission modulation of 5.2% which is four times greater than typical thermochromic cholesteric liquid ...
