“…For the ICTE and C-PEG, the first-stage weight loss above 100 °C is likely related to the volatilization of residual water and PC . Although the initial weight loss temperature of the ICTE was 100 °C, the weight loss rate (<0.5%) was almost negligible in plastic processing. , In this study, the preparation and molding of the ICTE were conducted at 92 °C, indicating that the ICTE remained highly stable during blending. Based on the processing temperature requirements of the ICTE and the typical operating temperature range of wearable devices, it can be concluded that the stability of the ICTE is satisfactory for both thermoplastic processing and normal use scenarios.…”

With the rapid advancement of artificial intelligence, there has been a surge of enthusiasm for flexible ionic conductors suitable for use in human−computer interaction. Complex preparation processes, difficulties to being efficiently molded, and disability in rapid integration are the main challenges faced by flexible ionic conductors in practical application. In this study, a simple, facile, and environmentally friendly approach involving melt transesterification and melt blending has been developed to produce ultrastretchable, highly ionically conductive, and easily processable poly(butylene succinate)-block-polyethylene glycol/propylene carbonate/sodium thiocyanate (PBS-b-PEG/PC/NaSCN) blendbased ionic conductive thermoplastic elastomers (ICTEs). Differential scanning calorimetry (DSC), X-ray diffraction (XRD), and Fourier infrared spectroscopy (FTIR) revealed that the excellent ionic conductivity of the ICTE could be attributed to the synergistic effects of poly(butylene succinate) (PBS) segments and propylene carbonate (PC) in constructing ionic conductive channels in the ICTE. The ICTE exhibited a tensile strength of 8.3 MPa and an elongation of 1790%, making it suitable for use in wearable devices. Based on its outstanding processability, shape stability at high temperatures, thermal stability during processing, and constant sensing performance, an ICTE-based fabric sensor was successfully fabricated using the melt spinning and weaving technique. This fabric sensor effectively demonstrated its capability to monitor human activities.

“…Therefore, the preparation of ionic conductive elastomers with good electrical conductivity, light transmission, self-adhesion, high mechanical strength and high tensile properties remains challenging. In our previous work, 35 we obtained an ionic conductive elastomer with high transparency and strong self-adhesion through one-step photopolymerization of an AA/ChCl-type PDES with N , N -dimethylacrylamide (DMA), although this elastomer has high mechanical strength (9.27 MPa) and good tensile properties (1071%). However, compared with the high tensile strength reported in the literature, 36–38 its mechanical strength needs to be further improved.…”

Flexible electronic devices have garnered increasing attention for their applications in wearable devices, biomedical systems, soft robots, and flexible displays. However, the current sensors face limitations regarding low sensitivity, poor stability, and inadequate adhesion bonding between stimuli‐responsive functional materials and flexible substrates. To overcome these challenges and enable the further development of sensor devices, surface modification of stimuli‐responsive materials with amyloid aggregates has emerged as a promising approach to enhance functionality and create superior multifunctional sensors. This review presents recent research advancements in the flexible sensors based on protein amyloid aggregation. The article begins by explaining the basic principles of protein amyloid aggregation, followed by outlining the process of preparing 1D to 3D amyloid‐based composite materials. Finally, it discusses the utilization of protein amyloid aggregation as a surface modification technique for developing flexible sensors. Based on this foundation, we identify the shortcomings associated with protein amyloid aggregate composites and propose possible solutions to address them. We believe that comprehensive investigations in this area will expedite the development of high‐performance flexible sensors with high sensitivity, high structural stability, and strong interface adhesion, especially the implantable flexible sensors for health monitoring.
