| Research Purpose

This project aims to developmonstrate large area printed electronic circuits and multi-sensor systems onto soft substrate by developing of various manufacturing processes, sensing ability of organic electronic devices to detect environmental, chemical, and biological signals. Human skin aAttachable integrated sensor platform for sensingof environmental and biological signals will be developed by interconnection techniques between soft circuit and processing chip. Based on developed technique, unification of human care will come true for environmental monitoring and auto diagnosis.
