Melamine sponge, also known as nano-sponge, is widely used an abrasive cleaner in our daily life. In this work, the fabrication of a wearable strain sensor for human motion detection first demonstrated with commercially available nano-sponge starting material. The key resistance sensitive material obtained by encapsulation carbonized (CNS) silicone resin. as-fabricated CNS/silicone highly to maximum gauge factor 18.42. addition, exhibits fast and reliable response various cyclic loading within range 0–15% frequency 0.01–1 Hz. Finally, device including joint motion, eye blinking, blood pulse breathing attaching corresponding parts body. consideration simple technique, low cost excellent sensing performance, believed have great potential next-generation devices detection.
