  • Temperature sensing device, temperature sensor using the same, and wearable device having the same
    Patent number: 10054496
    Abstract: A temperature sensing device, temperature sensor using the same and wearable device having the same. In one aspect, the temperature sensing device includes a first layer formed of a temperature sensing material. The resistance of the temperature sensing material is configured to vary in response to changes in temperature. The temperature sensing device further includes a second layer comprising silver nano-particles and a third layer formed of the temperature sensing material. The second layer is interposed between the first and third layers.
