Ultrasensitive Piezoelectric Sensor based on Polyimide Foam for Sound Recognition and Motion Monitoring

ACS Applied Materials & Interfaces, Journal Year: 2025, Volume and Issue: unknown

Published: Feb. 7, 2025

The ultrasensitive piezoelectric sensors with the capability of sound recognition have attracted extensive attention due to their unique characteristics. However, fabrication acoustic favorable flexibility and sensitivity via simple controllable methods remains a significant challenge. Herein, an adaptive sensor based on polyimide (PI) composite foams containing fluorine groups is developed. uniform porous morphology endows foam-based remarkable 0.9536 V/N over broad pressure range (2.5–12.5 N), rapid response recovery times (18 15 ms, respectively), outstanding durability (over 19,000 cycles). Moreover, are capable effectively monitoring human motions, generated output voltages reached ∼30 V for practical applications as intelligent household devices. In particular, exhibit excellent detecting wide sounds, indicating exceptional sensitivity. This work offers promising opportunities design development high-performance recognition, motion monitoring, self-powered wearable devices in extreme environments.

Smart‐Adhesive, Breathable and Waterproof Fibrous Electronic Skins

Advanced Science, Journal Year: 2024, Volume and Issue: unknown

Published: July 25, 2024

For the need of direct contact with skin, electronic skins (E-skins) should not only fulfill electric functions, but also ensure comfort during wearing, including permeability, waterproofness, and easy removal. Herein, study has developed a self-adhesive, detach-on-demand, breathable, waterproof E-skin (PDSC) for motion sensing wearable by electrospinning styrene-isoprene block copolymer rubber carbon black nanosheets as layer liner copolymers N, N-dimethylacrylamide, n-octadecyl acrylate lauryl methacrylate adhesive layer. The high elasticity microfiber network structure endow PDSC good sensitivity linearity strain sensing. hydrophobic crystallizable ensures robust, waterproof, detaching-on-demand skin adhesion. Meanwhile, fiber enables air water permeability. integration functions endows great potential human activities both performances.
