However, such a touch sensor has a problem that a large number of piezoelectric sensors are required in units of cells, which is expensive and complicated in lines. Accordingly, in recent years, a touch sensor for detecting a human body through a capacitive sensor has been proposed.

Then, the electrode 202 receives a high frequency to form a high frequency in the form of electromagnetic waves. Dielectric 204 absorbs high frequencies, which are converted to thermal energy and radiated. Here, the high frequency refers to approximately 100 MHz to 10 kHz. As described above, the touch sensor 200 of the present invention can perform a hot wire function as well as detecting a change in capacitance.

In addition, the voltage applied to the electrode 202 may be controlled using pulse width modulation (PWM). In this case, the electrode 202 is configured to have a resistance component, so that the electrode 202 generates heat by a current flowing through the electrode 202. The resistance value of the electrode 202 can be easily set using the law of Joule. Also in this case, the dielectric 204 may be omitted.

It is determined whether or not the temperature is exceeded (S195). As a result of the determination, when the temperature of the dielectric 204 measured by the temperature sensor 410 exceeds the preset allowable temperature, that is, the temperature is higher than necessary, the control unit 100 generates a high frequency or Control not to apply any more power (S198). Thereafter, the controller 100 controls the low frequency generator 201 to control the low frequency generator 201 to apply the low frequency to the touch sensor 200. If the temperature of the dielectric 204 measured by the temperature sensor 410 is lower than or equal to a preset allowable temperature, that is, the temperature of the dielectric 204 measured by the temperature sensor 410 is not higher than necessary, the control unit 100 includes a counting unit. The number of times that are not high temperature is counted from S300 (S196), and when the count number satisfies the predetermined number (S197), the operation S198 is performed.
