Anti-freezing multifunctional conductive hydrogels: from structure design to flexible electronic devices

“…To address this issue, antifreeze composite hydrogels have been developed by introducing both ions and polyol, which allows for high electrical conductivity, a wide working temperature range, and improved durability. Common composite systems include the NaCl/Gl system, [84][85][86] LiCl/Gl system, 87-89 KCl/Gl system, [90][91][92] NaCl/ EG system, 93 LiCl/EG system, 94,95 and CaCl 2 /sorbitol system. 96 There are significant differences in the mechanical and electrical properties between polyol-based hydrogels and complex salt-polyol-based hydrogels.…”

A low-hysteresis, self-adhesive and conductive PAA/PEDOT:PSS hydrogel enabled body-conformable electronics

“…Besides, an intimate, reliable, and unobstructed bio-electronic interface is essential for the stability of electrode devices and received signals for all wearable/implanted application scenarios. 5,[15][16][17] Sufficient adhesion and adaptive modulus can effectively avoid random impedance variations and data artifacts caused by the relative motion of the interface or even deformation. Moreover, inspired by the self-healing characteristic of human skin, it is highly desirable to endow conductive gels with the self-healing ability, 3,12,18 consequently improving their reliability.…”
