Description

Wearable device for measuring biosignals

This document relates to a wearable device, and more particularly, to a wearable device for measuring a biosignal.

As interest in health and medical care increases, a biosignal measurement function is also becoming more common in electronic devices. The electronic device may use a biosensor to measure a biosignal. For example, the electronic device may measure a biosignal such as an electrocardiogram, heart rate, or blood pressure by using a biosensor such as an electrocardiography (ECG) sensor or a photoplethysmogram (PPG) sensor.

In the case of a wearable device, a biosignal measurement function can be implemented more conveniently and accurately due to the wearable device characteristic. For example, the watch-type wearable device may measure various bio-signals (eg, electrocardiogram, heart rate, and/or blood pressure) of the user while being worn on the user's wrist.

As the biosignal measurement function becomes more common, the level of demand for functionality or usability of a wearable device for biosignal measurement is also increasing.

In the case of implementing a biosignal measurement function in the electronic device, a part in contact with the user's body may be required.

For example, when measuring the heart rate or blood pressure, an optical PPG sensor may be disposed on a portion in contact with the user's body and the heart rate or blood pressure may be measured using the PPG sensor. As another example, when measuring the electrocardiogram, the electrocardiogram according to the potential difference between the arms may be measured using electrodes in contact with the arms of the user.

In the case of a wearable device, functionality or usability may vary depending on a location where electrodes are disposed. For example, a watch-type wearable device may have spatial and design limitations when disposing electrodes for measuring biosignals due to their relatively small size. In addition, when the required number of electrodes increases, it may be difficult to arrange a plurality of electrodes at appropriate positions. Due to the increase in the number of electrodes, the aesthetic sense may be impaired, and the user's position for measuring biosignals may become inconvenient, and thus usability or functionality may be deteriorated.

According to an embodiment, when the number of electrodes disposed on the wearable device 100 increases, the types of measurable biosignals may increase. For example, in the case of a biosignal (eg, a bioimpedance signal) requiring 4-point touch-type measurement, the wearable device 100 includes four electrodes (eg, two first electrodes disposed on the rear surface of the frame 110 ). The corresponding biosignal may be measured using the 150 and the two second electrodes 160 disposed on the front surface of the strap part 130.

For example, when four electrodes are configured, one (eg, one first electrode 150) is connected to the ground, and two electrodes (eg, another first electrode 150 and one second electrode) are connected to the ground. The ECG signal is measured by combining the signals output from the two electrodes 160), but noise is removed by using a signal output from the remaining one of the four electrodes (eg, the second electrode 160 of the other one).

The non-conductive material may include not only a structure formed of a non-conductive material, but also a structure formed of a conductive material and then surface-treated with a non-conductive material.
