Recent Progress of Nanomesh Electrodes for Continuous Monitoring of Skin Electrical Resistance

We report on recent progress nanomesh electrodes that can be attached directly on the skin. In particular, we have continuously monitored the skin electrical resistance by nanomesh electrodes for a long period of time while maintaining the natural skin condition that does not inhibit water evaporation. The skin electrical resistance by nanomesh electrodes is inversely proportional to the transepidermal water loss, which is widely used as a method for directly evaluating the barrier function of the stratum corneum of the skin. Although transepidermal water loss could not be measured continuously for a long period of time, we have succeeded in visualizing dynamics of skin physiological functions by monitoring of the skin electrical resistance by nanomesh electrodes for 30 hours.
