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.

Silk fabrics have poor resistance to ultraviolet (UV) light and to wrinkles. To improve these properties, we propose a finishing method of coating the silk fabric surface with nano-silica (nano-SiO2). The results show that the UV protective factor (UPF) value could reach a maximum of 84.52 after finishing in 10 g/L nano-SiO2 and 20 g/L silane coupling agent (KH570) solution at 80℃. Moreover, the treated silk fabrics showed improved wrinkle resistance and hydrophobicity. The surface morphology and crosslink action of the treated silk fabrics were characterized by scanning electron microscope, energy dispersive spectrometer and Fourier transform infrared spectroscopy, which proved that nano-SiO2 particles were grafted on to the silk fabric. There was no apparent difference in color between untreated and treated silk fabrics. Thermal stability and cytotoxicity tests showed that the treated silk fabrics had good thermostability and cytocompatibility. The UPF value could be maintained at 77.31 after washing 20 times, which demonstrated that the treated silk fabrics had laundry resistance. Multifunctional silk fabrics with good hydrophobic properties and excellent UV and wrinkle resistance were developed, showing good prospects for their application in self-cleaning, protective and non-ironing clothes.
