Fully Printed Sensors for In Situ Temperature, Heat Flow, and Thermal Conductivity Measurements in Flexible Devices.Flexible temperature sensors allow temperature monitoring in wearable healthcare devices.  The versatility of this temperature sensor design is demonstrated for various applications, including in situ heat flux measurements, where a 2 mW cm-2 resolution is reached, and thermal conductivity measurements on polymer films as thin as 25 μm, with a wide range of accessible values from ∼0.1 to 0.8 W K-1 m-1.
