摘要:
A circuit and method for compensating for an electrode motion artifact in which the electrode motion artifact is generated because impedance between a subject and a measuring electrode changes during measurement of the subject's biosignal, and the electrode motion artifact can be differentially measured and an electrocardiogram signal can be compensated by introducing a predetermined voltage or an electric current to the subject. A circuit and method for compensating electrode motion artifact, which can differentially measure the difference information between impedance components by introducing a predetermined voltage or electric current to a subject, in association with the electrode motion artifact. In this instance, the impedance component is a component of electrode motion artifact and the electrode motion artifact is generated when measuring a biosignal.

A biological signal measuring apparatus is provided. The biological signal measuring apparatus includes a first unit measurer configured to measure a first biological signal of a subject based on an electrical characteristic difference between first electrodes contacting the skin of the subject, and a second unit measurer configured to measure a second biological signal of the subject based on an electrical characteristic difference between second electrodes contacting the skin of the subject at positions different from positions of the first electrodes. A plurality of unit measurers including at least the first unit measurer and the second unit measurer are arranged based on characteristics of contact parts of the first and second electrodes.

A blood vessel pressing cuff includes a strap surrounding a body part, a first actuator disposed on the strap and including a first shape memory alloy which changes to a first shape memorized in advance, at a temperature equal to or higher than a first temperature, and a second actuator disposed on the strap and including a second shape memory alloy which changes to a second shape memorized in advance, at a temperature equal to or higher than a second temperature that is different from the first temperature. If the first shape memory alloy changes to the first shape, pressure applied to the body part surrounded by the strap is increased. Even when the first shape memory alloy changes to the first shape, if the second shape memory alloy changes to the second shape, the pressure applied to the body part surrounded by the strap is reduced.
