A Highly Skin‐Conformal and Biodegradable Graphene‐Based Strain Sensor

For wearable sensors, realizing a strong and conformal contact with skin is essential to precisely detect human vital signals and enable human–machine interaction. Herein, a facile strategy is reported to fabricate a sensor with ultrahigh skin conformity by adopting a commercial make‐up accessory (nose film) as the substrate and graphene as the active materials. The wearable strain sensor can be pasted on human skin at the dermatoglyph level,...
