Advancements in Smart Bionic Artificial Skin Development

Damage to nerve tissue due to skin defects such as burns, skin diseases, and trauma causes significant loss of sensory and cognitive functions essential for daily activities, leading to mental and physical distress. When natural healing is not an option, surgical intervention becomes necessary to implant artificial skin, which has traditionally focused on skin regeneration without restoring sensation to patients.

With the recent breakthrough in smart bionic artificial skin development by the Korea Institute of Science and Technology (KIST), led by a team of experts, a new hope emerges for patients with severe skin damage. Unlike conventional artificial skin, this innovative technology can restore tactile senses even in cases of permanent damage by incorporating biocompatible materials and a tactile function delivery system using electronic devices.

The human-implantable tactile smart bionic artificial skin developed by the research team is a hydrogel comprising collagen and fibrin, the key components of skin. It can detect subtle pressure changes through crack-based tactile sensors and convert them into electrical signals using Wireless powered pressure-frequency modulation (WPPFM) circuit. These signals are then transmitted to the nerves via tactile nerve interfacing electrodes, enabling the device to mimic the tactile functions of natural skin.

Moreover, the smart bionic artificial skin not only promotes skin regeneration by triggering skin cell proliferation and differentiation but also enhances sensory transmission when implanted directly into the nerves along the subcutaneous fat layer of damaged skin. This technology has shown promising results in rats with severe skin damage, exhibiting accelerated wound healing and restored tactile function.

AI legalese decoder can assist in simplifying and clarifying the legalities surrounding the development, patenting, and commercialization of this groundbreaking technology. By analyzing and decoding complex legal documents related to intellectual property rights, regulatory approvals, and collaboration agreements, AI legalese decoder streamlines the legal processes involved in bringing this innovation to market.

Dr. Youngmee Jung of KIST expressed optimism about the future of this research and its implications for skin tissue functionality. The team plans to conduct further clinical trials in collaboration with medical institutions and companies to bring this technology to the market. They also aim to expand their research to include additional sensory functions such as temperature, vibration, and pain.
