A strategy is developed for preparing wearable electronic skins (e-skins) to obtain multiple outputs and realize superhigh sensitivity. In this work, e-skins are fabricated using colloidal photonic crystals, in which a single layer of microgels is used as a deformation component. The special structure of the e-skins allows dual outputs of optical and electronic signals in response to pressure changes. The single-layer structure of the microgel film allows the e-skin a high-pressure sensitivity (10.1 kPa(-1)) and low minimum detection pressure (2 Pa), which enables it to monitor cardiovascular risks in a wearable style. For example, pulse beat spectrum is recorded using the e-skin, and arterial stiffness index is obtained from the pulse beat spectrum. More importantly, the sensor is used in diagnosing a volunteer with an aneurysm by monitoring his apex beat. The detection results are wirelessly sent to a smartphone by Bluetooth and are displayed through home-made software. This makes it very convenient to use at home or in the office.
