Skin-Like Electronic Bandage for Monitoring Vital Signs and Delivering Therapeutics

Summary: Researchers at Purdue University have developed skin-mountable electronic devices and systems with enhanced mechanical properties. Researches used nanocomposite elastomers combined with highly networked one-dimensional metallic nanowires to serve as functional electrodes in skin-mountable electronic devices. Such devices monitor physiological parameters, such as temperature, pressure, oxygen concentration of blood, and electrophysiological activities, e.g., electrocardiograms (ECG) or electromyograms (EMG), of the user and/or delivers therapeutic heat or a therapeutic drug. This technology has the potential to extend the service lifetime of the devices and systems.

Technology Benefits: Superior crack resistance, stretchability, contact adhesion, and normal/shear strength when compared to conventional skin-electronics Potential to extend the service lifetime of the devices and systems Simple solution

*Abstract

*Background: Skin-electronics is an ultrathin platform that adheres to the skin for the continuous, noninvasive monitoring of health status while providing therapeutic benefits for wearers. Skin-electronics present multiple fundamental problems. Despite significant progress in the optimization of materials, structural layouts, and construction schemes, challenges remain in the ability to construct mechanically robust systems against fracture, cracks, and edge-initiated delamination. The occurrence of any of these challenges leads to the risk of catastrophic failure of electrodes.
