Abstract
An embodiment is a biosignal measurement system including an electrode configured to be in contact with skin of a first part of four limbs of a measurement subject, a first controller configured to obtain an electrocardiogram signal of the measurement subject based on a biopotential detected by the electrode, a perspiration sensor configured to measure electrical characteristics derived from perspiration of a second part of the four limbs of the measurement subject, and a second controller configured to calculate a mental perspiration amount of the measurement subject based on the electrical characteristics measured by the perspiration sensor.

A biosignal measurement system comprising:
- an electrode configured to be in contact with skin of a first part of four limbs of a measurement subject;
- a first controller configured to obtain an electrocardiogram signal of the measurement subject based on a biopotential detected by the electrode;
- a perspiration sensor configured to measure electrical characteristics derived from perspiration of a second part of the four limbs of the measurement subject;
- and
- a second controller configured to calculate a mental perspiration amount of the measurement subject based on the electrical characteristics measured by the perspiration sensor.
A method for measuring biosignals, comprising:
- contacting an electrode with skin of a first part of four limbs of a measurement subject;
- obtaining, by a first controller, an electrocardiogram signal of the measurement subject based on a biopotential detected by the electrode;
- measuring, by a perspiration sensor, electrical characteristics derived from perspiration of a second part of the four limbs of the measurement subject;
- and
- calculating, by a second controller, a mental perspiration amount of the measurement subject based on the electrical characteristics measured by the perspiration sensor.
A biosignal measurement system comprising:
- a first sensor device configured to attach to a first limb of a measurement subject;
- a second sensor device configured to attach to a second limb of the measurement subject;
- wherein the first sensor device includes a first electrode configured to contact skin of the first limb;
- wherein the second sensor device includes:
- a second electrode configured to contact skin of the second limb;
- a controller configured to obtain an electrocardiogram signal of the measurement subject based on biopotentials detected by the first and second electrodes;
- a perspiration sensor configured to measure electrical characteristics of the skin of the second limb;
- and
- a processor configured to determine a perspiration level of the measurement subject based on the measured electrical characteristics.
