Patent ID: 8606353

Claim:
An apparatus for measuring biological signals, comprising: a multi-electrode module comprising a non-conductive patch and a sensor array including a ground electrode and a plurality of individual electrodes; an electrode selection unit to select a plurality of electrode pairs, including a reference electrode and a measurement electrode, from the plurality of individual electrodes based on a type of biological signal measured; and a signal processing unit to obtain the biological signals from the plurality of electrode pairs, wherein the signal processing unit obtains respective biological signals concurrently based on the selected plurality of individual electrodes, with the ground electrode, and each of the selected plurality of individual electrodes being different electrodes and the ground electrode being monitored during the measuring of the heart rate and measurement for the electrocardiograph analysis, wherein the electrode selection unit comprises: an operation unit to generate a predetermined control signal based on the type of the biological signal measured based on a user's input; a measurement signal selection unit to select an individual electrode placed at a center of the plurality of individual electrodes, disposed in a substantially circular arc, as the reference electrode for a reference signal, and sequentially selecting from the plurality of individual electrodes as the measurement electrode for a measurement signal based on the individual electrode selected to be the reference electrode; a measurement signal generating unit to select the individual electrode as the reference electrode for the reference signal and selecting the plurality of individual electrodes disposed on the substantially circular arc as the measurement electrode for the measurement signal; and a switch unit, in response to the control signal, to selectively connect the multi-electrode module to the measurement signal selection unit or the measurement signal generating unit.
