Abstract
A wearable sensor includes: a base member which is worn on a body of a wearer; a hole-like flow passage which penetrates through the base member; a sensor part which detects a signal as to electrical characteristics of a solution inside the flow passage; and a heater which is located in the base member in such a way as to enclose the flow passage.
Claims10
A wearable sensor comprising:
- a base member configured to be worn on a body of a wearer;
- a flow passage which penetrates through the base member;
- a first sensor part configured to detect a signal as to electrical characteristics of a solution inside the flow passage;
- and
- a heater which in the base member, wherein the heater encloses the flow passage.

A perspiration analysis device comprising:
- a wearable sensor comprising:
- a base member configured to be worn on a body of a wearer;
- a flow passage which penetrates through the base member;
- a first sensor part configured to detect a signal as to electrical characteristics of a solution inside the flow passage;
- a heater which in the base member, wherein the heater encloses the flow passage;
- and
- a second sensor part for detection of perspiration that is secreted from skin of the wearer and flows into the flow passage
- a component concentration calculation part being configured to calculate a concentration of an analysis target component from an electrical signal which is detected by the first sensor part;
- and
- a power supply control part being configured to supply power to the heater and heat the heater when acquisition of the concentration of the analysis target component has been finished, wherein when the second sensor part detects that the perspiration secreted from skin of the wearer has reached a position of the first sensor part, the power supply control part determines that the acquisition of the concentration of the analysis target component has been finished.
