Skin is the largest organ in human body and requires proper dressing to facilitate healing after an injury. Wounds on movable parts, such as elbow, knee, wrist, neck, usually undergo delayed inefficient due frequent movements. To better accommodate wounds, a variety of functional hydrogels have been successfully developed used flexible wound dressings. On one hand, mechanical properties, adhesion, stretchability, self-healing, make these suitable for mobile wounds promote process; other bioactivities, antibacterial antioxidant performance, could further accelerate process. In this review, we focus recent advances hydrogel-based dressings propose challenges perspectives

In recent years, portable and wearable personal electronic devices have rapidly developed with increasing mass production rising energy consumption, creating an crisis. Using batteries supercapacitors limited lifespans environmental hazards drives the need to find new, environmentally friendly, renewable sources. One idea is harness of human motion convert it into electrical using harvesting devices—piezoelectric nanogenerators (PENGs), triboelectric (TENGs) hybrids. They are characterized by a wide variety features, such as lightness, flexibility, low cost, richness materials, many more. These offer opportunity use new technologies IoT, AI or HMI create smart self-powered sensors, actuators, implantable/wearable devices. This review focuses on examples PENGs, TENGs hybrid for implantable systems. The basic mechanisms operation, micro/nano-scale material selection manufacturing processes selected discussed. Current challenges outlook future also

The current wearable devices are largely rigid and bulky, which calls for the development of next-generation soft biocompatible technologies. Another limitation is that conventional generally powered by thick non-compliant batteries, hindering miniaturization improvement electronics. Hydrogels have attracted tremendous attention in field bioelectronics due to their tissue-like properties, can minimize mechanical mismatch between flexible biological tissues. Moreover, take advantage physical chemical energy from human body or ambient environment, such as motions, heat energy, biofuel, water wind power nature, more novel technology portable supply has been carried out, facilitating bioelectronics. In this review, recent advances self-powered based on hydrogels summarized. Firstly, excellent properties introduced, including prominent self-healing high conductivity incorporation conductive polymers additives, interfacial adhesion functionality, biocompatibility, antibacterial properties. Then, several strategies harvesting discussed, triboelectric nanogenerators (TENGs), piezoelectric (PENGs), thermoelectric (TEGs), biofuel cells (BFCs), hydrovoltaics, antennas, hydrogel-based batteries. Next, some representative applications illustrated (i.e., motion monitoring, healthcare monitoring therapies, neural stimulation human-machine interaction). Finally, a brief summary outlook hydrogel presented.
