Laser-Microstructured Piezocapacitive System: A Wireless Platform for Quantitative Assessment of Wound Flatness

Postoperative wound management is a critical determinant of recovery in plastic surgery and burn care, where accurate assessment of wound flatness plays a central role. Yet current evaluation remains largely subjective, relying onclinical experience rather than quantitative metrics. Here, we present a laser-microstructured piezocapacitive system: a compact, fully integrated wireless platform that is encapsulated in soft, biocompatible materials for the high-resolution, real-time monitoring of wound topography. The device incorporates a tetherless, femtosecond-laser-fabricated microstructured sensor that achieves submillimeter resolution (
