Self-Healing, Degradable, and Biobased Polyurethane Elastomer for High-Performance Piezoresistive Pressure Sensors with a Hump-like Microstructure

Langmuir, Journal Year: 2025, Volume and Issue: unknown

Published: Feb. 19, 2025

Flexible sensors are widely applied in the fields of electronic skins and wearable devices, yet it is still a big challenge to effectively prolong lifespan damaged reduce environmental pollution caused by discarded after updating upgrading. Herein, we proposed self-healing, degradable, biobased polyurethane elastomer for high-performance flexible pressure sensors. The synthesized using fatty diamine as chain extender possessed high tensile strength 13.25 MPa an elongation at break 830%, self-healing efficiency reached up 109.2%. Additionally, could be fully degraded within 7 days 1 mol L-1 NaOH solution with assistance ethanol. elastomer-based sensor hump-like microstructure was fabricated reduced graphene oxide conductive material via simple template method. showed sensitivity 9.448 kPa-1, large sensing range 0-300 kPa, short response/recovery time 40/80 ms, good stability 14,000 cycles. Moreover, utilized monitor different human motions, including muscle contraction, joint bending, swallowing, voice recognition, pulse beat. Importantly, even being severely damaged, able recover its function detecting motions. findings this research provide strategy sustainable development environmentally friendly functional elastomers

Ultra‐Broad‐Range Pressure Sensing Enabled by Synchronous‐Compression Mechanism Based on Microvilli‐Microstructures Sensor

Advanced Functional Materials, Journal Year: 2025, Volume and Issue: unknown

Published: March 27, 2025

Abstract A sensor which is able to detect both the high‐ pressure and subtle crucial for applications such as physiological health monitoring human‐machine interactions. However, current sensors often struggle meet these requirements, they usually rely on a single compression mechanism. In this study, microvilli‐microstructures reported capable of tracking ultra‐broad‐range pressures based synchronous‐compression The mechanism includes: i) increase microvilli‐induced electron‐transfer, ii) microstructure contact area, iii) decrease multi‐walled carbon nanotubes spacing. At high‐pressure stages, mechanisms contribute synchronously changes in resistance. Hence, can measure 5 kPa change under extremely (750 kPa) conditions meniscus simulation, where commercial fails. This exhibits high sensitivity 58.88 −1 , an ultra‐broad working range from 50 Pa up 782.5 kPa, rapid response time 9 ms, long‐duration (under 250 pressure, cycling 10,000 times). flexible also shows versatility potential various applications. proposed here inspire future designs high‐performance sensors.

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

Published: April 18, 2025

Inspired by the structure of Setaria viridis and based on guidance molecular dynamics simulations, a hierarchical nanospike micrometer-sized coaxial fibers has been designed at scale. A piezoresistive composite membrane in situ-grown PDA-PPy TPU@PES fiber prepared, exhibiting good anticreep performance, high sensitivity, fast response. The matrix material is as fibers, which consist an inner PES core that provides mechanical support outer thermoplastic polyurethane shell offers large specific surface area rich graft reaction sites. semiconductor phase constructs interlocking structured forming multihierarchical conducting network. sensor constructed with this exhibits ultrahigh sensitivity (27.1 kPa-1) quick response (23.1 ms time 26.3 recovery time). Furthermore, chemical grafting process ensures stable interface between creating covalent hydrogen bonds. This not only prevents instability but also demonstrates excellent signal performance dynamic stability (10,000 cycles). Monitoring changes renal pelvic pressure 3D-printed artificial pelvis was performed, confirming its practicality for medical monitoring.
