Abstract
Nanosensors play an irreplaceable role in environmental and health monitoring fields. Single-function sensor can’t meet the application requirements of increasingly complicated environment. In this work, a novel multifunctional self-powered visualization system (SVS) by photovoltaic effect and contact-electrification has been demonstrated. The fabricated SVS can detect ultraviolet (UV) light and mechanical signals without any external power，which can visualize and distinguish both signals accurately. The SVS shows excellent photoresponse properties as a self-powered UV photodetector, with a high sensitivity over 107, a rapid rise/decay time (less than 0.4 s), and a low detection UV light intensity of 0.24 mW/cm2. In addition, the SVS can detect gentle wind (1.0 m/s) as a self-powered wind velocity sensor system. It has been applied for the real-time environment monitoring of UV light and wind. The visualizing function of the SVS for different environmental signals has wide potential applications in human-electronic interfacing, Internet of Things, real-time online inspection and other intelligent fields.
