“…Fortunately, research on friction nanogenerators may provide a solution to this dilemma. 79 The friction nanogenerator provides energy through the coupling of friction electrification and electrostatic effects and the thin layer electrode. Compared with the energy allocation mode that requires an external power supply, the friction nanogenerator can realize the independent supply of energy from the inside during the operation of the equipment and will not restrict the user when there is no power.…”

As wearable health devices have the ability of intelligent monitoring, they are becoming cutting-edge technology in medical and health fields. However, the simplification of functions limits their further development. In addition, soft robotics with actuation functions can achieve therapeutic effects by doing external work, but their monitoring function is not sufficiently developed. The efficient integration of the two can guide future development. The functional integration of actuation and sensing can not only monitor the human body and surrounding environment but also realize actuation and assistance. Recent evidence shows that emerging wearable soft robotics can become the future of personalized medical treatment. In this Perspective, the comprehensive development in the field of actuators for simple structure soft robotics and the field of wearable application sensors are introduced, as well as their manufacturing processes and various potential medical applications. Furthermore, the challenges faced in this field are discussed, and future development directions are proposed.

Triboelectric nanogenerators (TENGs) developed from eco-friendly natural materials rather than traditional electronic materials are more favorable for biocompatible applications and for use in sustainable life-cycle analysis. Silk fibroin (SF) has emerged as an abundant natural biomaterial that shows great potential in the preparation of TENGs. Silk-based triboelectric nanogenerators (SF-TENGs) have green energy harvesting properties, are environmentally friendly, are biocompatible, are not fully present in conventional TENGs, and are important for the next generation of selfpowered electronic devices. In this review, the latest progress in SF-TENGs, including their applied materials, structural properties, manufacturing processes, and application scenarios, is discussed. These SF-TENGs show great potential for use in emerging energy and electronic applications as well as smart living and medical assistance. In addition, the potential value of SF-TENGs has been further explored, and the possibility and main challenges of expanding and applying SF-TENGs to the field of microneedles (MNs) are discussed.

“…By adding organic reagents like EG (ethylene glycol) or glycerol to hydrogels, numerous antifreezing and nondrying organic hydrogels have recently been studied by researchers. 10,11 For example, Zhao et al 12 reported the antifreezing conductive organic hydrogel with glycerol/ water binary solvent as the medium, and the resulting organic hydrogel showed a high tensile strain (900%) and strain sensitivity (GF = 39.4). In addition, Yu and colleagues reported an antifreezing organic hydrogel with CaCl 2 /sorbitol solution as the medium, it has good tensile properties and does not deform at low temperatures.…”

Conductive hydrogel is a novel material that can be used to prepare flexible wearable strain sensors. It paves the way for future uses in electronic skin, human‐computer interaction, and personalized medical monitoring. However, because the majority of conductive hydrogels use pure water as their medium, they will freeze at low temperatures. It will inevitably lose water at room temperature. We developed a PAM/SA/MXene organic hydrogel (denoted as PSMOH). First, MXene nanosheets were added as conductive filler into the double network polymer hydrogel, which was composed of polyacrylamide (PAM) and sodium alginate (SA), we denoted as PSMH. And then immerse the prepared PSMH in a glycerol solution using a solvent displacement method to obtain PSMOH. Even if at extreme temperatures (−30°C), the prepared PSMOH has a strong antifreezing ability and can retain moisture for 8 days. The sensor also has excellent mechanical properties (tensile strain is 1579%), self‐adhesive property, excellent sensitivity (gauge factor is 49.92), low detection limit (1% strain), and excellent fatigue resistance (800 cycles at 30% strain). As a result, the hydrogel can be assembled into a flexible wearable sensor for real‐time monitoring of human motions and other activities.
