摘要

The comprehensive implementation of sustainable development strategies has brought the preservation of cultural relics to the forefront, necessitating advanced electronic systems capable of real-time monitoring of temperature and humidity conditions for these invaluable artifacts. To address the critical gap in real-time ambient environmental monitoring for cultural relics, we present a self-powered nanopaper-based sensor system with exceptional performance characteristics: precise temperature monitoring (± 2 °C accuracy) and reliable humidity detection (± 5% accuracy) in real-time, combining merits of high sensitivity, rapid response, long-term durability, and eco-friendly materials, specifically engineered to meet the stringent requirements of cultural relic conservation. In addition to substantial power consumption reduction, the triboelectric nano-generator (TENG), inducing by triboelectricity between human’s skin and the nanopaper, enables the device anti-theft capabilities. The outstanding comprehensive performance of our sensing array establishes a promising foundation for the development of self-powered sensors in the field of heritage conservation.
