N1 - Funding Information:
We developed a tip-opened PMN that can analyze bio-information around the tip part of the needles, and an Ag/AgCl reference electrode that is thin and flexible with sufficient stability for long term monitoring of bio-information. Then the patch-type device was fabricated combining them and the monitoring of TEP, useful indicator of skin health status, was realized. We plan to use this device to analyze reactive oxygen species.

N2 - 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.
