In this paper, we report a humidity sensor made by nanomesh electrodes and nanomesh sensitive materials. The porous structure makes the sensor gas-permeable and increases the surface area, leading to high sensitivity. The gas-permeability suppresses the skin inflammation and allows natural evaporation of sweat, making a same condition as bare skin. The mechanical durability of the sensor makes it suitable for on-skin monitoring.
