Electronic skin for precision medicine

Inspired by the seamless integration of sensory skins and skeletal muscles in vertebrates, this study presents the design and implementation of bio-inspired soft robots. These robots, equipped with electronic skins (e-skin) and artificial muscles, aim to revolutionize medical technology by providing minimally invasive, multifunctional, and biocompatible solutions for diagnosis, treatment, and rehabilitation.
The e-skin layer, composed of functional nanocomposites, mimics the diverse receptor functions of human skin, enabling the detection of various stimuli such as touch, pressure, temperature, and chemicals. Integrated with a poly(N-isopropylacrylamide) (PNIPAM) hydrogel-based artificial muscle, these robots can adapt their structure and perform complex motions in response to environmental changes. The study highlights several innovative applications, including a robotic cuff for blood pressure monitoring, a gripper for bladder volume tracking and stimulation, an ingestible robot for pH sensing and drug delivery, and a patch for cardiac function assessment and electrotherapy. These bio-inspired robots operate wirelessly, utilizing battery-free modules for untethered functionality. The ability to morph and conform to biological tissues enhances their effectiveness and safety in medical applications. The integration of actuation and sensing capabilities within a single platform offers unprecedented precision and adaptability in therapeutic interventions.
The development of these soft robots marks a significant advancement in electronic implants, promising improved outcomes in surgeries, chronic disease management, and rehabilitation. Future research will focus on optimizing material properties, enhancing biocompatibility, and expanding the range of medical applications to fully harness the potential of these innovative technologies.
