Wearable intelligent sensor materials have broad application prospects for human health detection and robot kinematics. 3D structure sensors have the advantages of high sensitivity, a wide detection range, and high strength, as is widely reported in existing research. Here, a sandwich structure involving an encapsulation layer, a 3D conductive network, and an encapsulation layer is prepared. Polyaniline acts as an active conductive filler for the 3D conductive network, while silk fibroin and poly (lactic‐co‐glycolic acid) are used to form a network for carrying conductive materials. Additionally, K‐carrageenan is added to encapsulate the 3D conductive network and prepare a high‐performance green skin sensor. The sensor exhibits high sensitivity (2.54 kPa−1) and a wide linear detection range (165.3 kPa). In addition, the pressure sensor possesses excellent durability (>2000 cycles) and a fast response time of 160 ms. Moreover, the sensor is compatible and biodegradable and encapsulated by a nontoxic water‐soluble polymer. On this basis, skin sensors for health monitoring systems and intelligent interactive systems are reported, thus enabling future applications in medical detection and human–machine interaction.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
