Abstract

The monitoring of bio-information through skin with wearable devices has been attracted as an advanced mean for daily health management. We developed a patch-type wearable device composed of a novel porous microneedle (PMN) and a flexible, stable Ag/AgCl reference electrodes. The whole of PMN contains 3D microchannels, and serves as a minimally invasive interface for the transdermal transport of molecules and ions. By using the flexible PMN patch, we realized the monitoring of the transepidermal potential (TEP), a potential difference generated along the thickness direction of the epidermis, which is an useful indicator of skin health status.
