BIOLOGICAL INFORMATION DETECTION SENSOR, ELECTRIC APPARATUS USING THEREOF AND BIOLOGICAL INFORMATION DETECTION METHOD
First Claim
1. A biological information detection sensor comprising:
- a smell detection means which senses a specific smell;
a moisture detection means which senses moisture;
a temperature detection means which detects an ambient temperature; and
a switching means which switches between the smell detection means and the moisture detection means based on detection results of the temperature detection means.

Abstract
A biological information detection sensor is provided by which it is possible to integrate multiple detection means, and it is possible to measure the biological information that is necessary in accordance with the usage state of the sensor used by the user while avoiding redundant information. The biological information detection sensor includes: a skin condition detection portion measuring at least one of a capacitance and an electric resistance change between engaged comb electrodes; a smell component detection portion measuring an electric resistance in accordance with objects absorbed on a selective sensitive membrane which is formed on a portion of the engaged comb electrodes; a temperature detection portion measuring an ambient temperature based on an electromotive force generated by a thermocouple which is formed by using at least two kinds of metallic materials and which is formed on a portion of the engaged comb electrodes; a switching means SW which compares the electromotive force generated by the thermocouple due to changes of the ambient temperature to a predetermined threshold, detects a contact state with an object having a heat source such as a biological body based on a comparison result and conducts switching operation of ON and OFF of the skin condition detection portion and the smell component detection portion based on the contact state.
