“…In view of the light weight, thinness, and good deformability of polymers, polymer-based ionic sensors have been the most commonly used. − Incorporating biocompatible biodegradable polymers with conductive polymers to develop conductive polymeric composites for tissue engineering applications is a very important application direction of polymer-based sensors . Ionic polymer sensors (IPSs) typically consist of two layers of conductive electrodes sandwiching an ionic polymer matrix. , When deformed, the ions inside the ionic polymer matrix will migrate directionally under the action of pressure gradient and form an electric double layer (EDL) along the interface between the electrodes and the matrix to realize the conversion of ionic signals to electrical signals. , Therefore, the area of the formed EDL will affect the amplitude of the output voltage, which is usually determined by the preparation process.…”

Ionic polymer sensors (IPSs) have broad application prospects in health monitoring, environmental perception, and human−computer interaction. The performance of IPSs with chemically prepared electrodes is generally superior to that with physically prepared electrodes due to the area difference of the electric double layer (EDL), but the effects of the electrode characteristics prepared by chemical methods on the performance of IPSs have not been revealed. Therefore, in this paper, we studied the impact of the characteristics of chemically prepared electrodes on the performance of IPSs and realized the performance optimization of IPSs through electrode characteristic regulation. By controlling the matrix surface roughening, immersion reduction plating (IRP) cycles, and electroplating (EP) time, the sensing performances of IPS samples with different electrode interface roughnesses, electrode penetration depths, and surface resistances were investigated, respectively. The experimental results indicated that the response voltage of the IPS can be improved by increasing the electrode interface roughness and the electrode penetration depth and reducing the surface resistance. In addition, we have proven that the sensing performance of the IPS is determined by its intrinsic capacitance characteristics. Through coupling electrode characteristic regulations such as roughening and increasing IRP cycles and EP time, a high-performance IPS was obtained, and its response amplitude was improved by 237.8%. The obtained high-performance sensor has been applied in human motion detection, which has good potential to develop wearable devices with high stability for physiological activity monitoring.

Tissue repair and reconstruction are a clinical difficulty. Bioelectricity has been identified as a critical factor in supporting tissue and cell viability during the repair process, presenting substantial potential for clinical application. This review delves into various sources of electrical stimulation and identifies appropriate electrode materials for clinical use. It also highlights the biological mechanisms of electrical stimulation at both the subcellular and cellular levels, elucidating how these interactions facilitate the repair and regeneration processes across different organs. Moreover, specific electrode materials and stimulation sources are outlined, detailing their impact on cellular activity. The future development trends are projected from two perspectives: the optimization of equipment performance and the fulfillment of clinical demands, focusing on the feasibility, safety, and cost‐effectiveness of technologies.
