“…Some researchers try to monitor wound healing by detecting the wound area. For example, Chen et al [ 196 ] prepared HSa hydrogels in simple steps using chitosan quaternary ammonium salt (HACC) and sodium alginate (SA) as raw materials. HACC and SA form a "Magic Cube" like structure through the electrostatic interaction between the positive charge of the amino group in HACC and the negative charge of the carboxylic acid group in SA, which can arbitrarily transform like a Rubik's cube.…”

Growing health awareness triggers the public’s concern about health problems. People want a timely and comprehensive picture of their condition without frequent trips to the hospital for costly and cumbersome general check-ups. The wearable technique provides a continuous measurement method for health monitoring by tracking a person’s physiological data and analyzing it locally or remotely. During the health monitoring process, different kinds of sensors convert physiological signals into electrical or optical signals that can be recorded and transmitted, consequently playing a crucial role in wearable techniques. Wearable application scenarios usually require sensors to possess excellent flexibility and stretchability. Thus, designing flexible and stretchable sensors with reliable performance is the key to wearable technology. Smart composite hydrogels, which have tunable electrical properties, mechanical properties, biocompatibility, and multi-stimulus sensitivity, are one of the best sensitive materials for wearable health monitoring. This review summarizes the common synthetic and performance optimization strategies of smart composite hydrogels and focuses on the current application of smart composite hydrogels in the field of wearable health monitoring.

“…Due to the excellent performance of CHs in biosensors, some CHs with real-time detection of the wound physiological state have also been developed. An obvious example is that the resistance of the CHs applied to the human body changes with tissue movement 25,122,[170][171][172] or temperature changes. 16,36,173 For example, in a small pressure strain range, the pressure sensitivity of a hydrogel based on a polyvinyl alcohol/acrylamideionic liquid is as high as 9.18 kPa −1 .…”

“…221,222 Alginate saline gel has electrical conductivity, and its resistance can be used to calculate the hydrogel deformation to evaluate the wound state, providing more accurate information for wound care and treatment. 223,224 Some researchers used nanosheets to endow alginate gel with conductivity and high sensitivity. Based on this technique, a stable alginate gel sensor was fabricated.…”
