Title:
SHEET HAVING HEAT GENERATING FUNCTION
Document Type and Number:
Japanese Patent JP2019067767
Kind Code:
A
Abstract:
To provide a device which warms a surface of a living body required to be warmed at necessary timing at any place indoors and outdoors or the sea without causing low temperature burns.SOLUTION: An antenna 11, a receiving control circuit 12 electrically connected to the antenna 11, a power source circuit 13 connected to the receiving control circuit 12, a heater driver circuit 15 electrically connected to the power source circuit 13, and a heater 14 electrically connected to the heater driver circuit 15 are provided on a sheet 10. In the case of using an electromagnetic coupling method or an electromagnetic induction method (for example, a band of 135 kHz or lower, and a 13.56 MHz band) as a transmission method, a conductive film which functions as the antenna 11 is formed to have a circular form (for example, a loop antenna) or a helical form (for example, a spiral antenna) in order to utilize electromagnetic induction that occurs with a change in electric field density.SELECTED DRAWING: Figure 1
