A facile and passive multiply flexible thin‐film sensor is demonstrated based on thermoelectric effects in graphene. The sensor is highly conductive, free‐standing, flexible, and elastic. It senses heat and cold, and measures heated/cooled areas; it also discerns human touch from other pressures, locates human touch, and measures pressure levels. All of these sensing abilities are demonstrated without any internal/external power supply.
