Flexible sensors (FSs) hold great potential in wearable and intelligent equipment, but the preparation of degradable and multimodal FSs is urgently demanded, which may simplify the sensor matrix and reduce electronic waste. Here in this work, a multimodal and degradable FS was fabricated by transferring laser-induced porous carbon onto starch film. The obtained sensor showed three modes that can detect strain (with gauge factor (GF) = 134.2, response time of 130 ms, and stability >1000 times), temperature (25–90 °C), and pressure (0–250 kPa). The sensor can be used for monitoring human motions, detection of spatial pressure, and multiple stimuli. More importantly, the sensor was demonstrated to be degradable in water, suggesting it is a “green” electronic device being free of electronic pollution. This kind of multimodal and degradable FS may find wide applications in health and sports monitoring, flexible electronics, artificial intelligence, and so on.
