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.
Claims20
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 perspiration inside the flow passage;
- and
- a heater which is located in the base member, wherein the heater encloses the flow passage, wherein the heater is configured to cause the perspiration to move away from the first sensor part to an opening of the flow passage that is opposite to the body of the wearer, wherein the heater surrounds the first sensor part.

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 perspiration inside the flow passage;
- and
- a heater which is located in the base member, wherein the heater encloses the flow passage, wherein the heater surrounds the first sensor part;
- a component concentration calculation part 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 configured to supply power to the heater and heat the heater in response to determining that acquisition of the concentration of the analysis target component has been finished to move the perspiration away from the first sensor part to an opening of the flow passage that is opposite to the body of the wearer.

A perspiration analysis device comprising:
- a wearable sensor comprising:
- a base member configured to be worn on a body of a wearer and to face skin of the wearer;
- a flow passage which penetrates through the base member, wherein a first opening of the flow passage is configured to face the skin of the wearer;
- a first sensor part configured to detect an electrical signal originating from an analysis target component in perspiration that is secreted from the skin of the wearer and flows into the flow passage;
- a heater which is located in the base member, wherein the heater encloses the flow passage from a periphery of the first opening to a position of the first sensor part inside the flow passage;
- and
- a second sensor part for detection of the perspiration that is secreted from skin of the wearer and flows into the flow passage, the second sensor part being located in a position inside the flow passage neighboring the first sensor part, wherein at least an inner wall of the flow passage is hydrophilic;
- a component concentration calculation part configured to calculate a concentration of the analysis target component from an electrical signal which is detected by the first sensor part;
- and
- a power supply control part configured to supply power to the heater and heat the heater in response to determining that acquisition of the concentration of the analysis target component has been finished to move the perspiration away from the first sensor part to an opening of the flow passage that is opposite to the body of the wearer, wherein when the second sensor part detects that the perspiration secreted from the 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.
