A physiological signal collection unit is used for measuring physiological signals about a subject covered by hairs with a physiological signal measuring apparatus, and has an elastic constraint and at least one detector. The elastic constraint adapts for putting at the subject, and has holes. The detector has an electric circuit foundation plate which forming a through hole, and a connector setting on the electric circuit foundation plate with at least one signal collection element. An external diameter of the electric circuit foundation plate is bigger or equal to the aperture of the hole of the elastic constraint. When we start to use the physiological signal collection unit, let some hairs from the subject path through the through hole, let the electric circuit foundation plate path through the hole and be between the elastic constraint and the subject, and let the signal collection element contact the skin of the subject. Then, the physiological signal measuring apparatus connects with the connector and controls the signal collection element operate for obtaining physiological signals.一種生理訊號蒐集單元,搭配一生理訊號量測設備量測一覆蓋有毛髮之受測部位的生理訊號,並包含一彈性束縛體及至少一探頭。彈性束縛體供套戴於受測部位,開設有穿孔。探頭包括一圍繞界定出一通孔的電路基板,及設於該電路基板的電連接器與訊號蒐集元件。電路基板的外徑大於等於該彈性束縛體之穿孔的孔徑。使用時,受測部位之毛髮成束地穿伸於該電路基板的通孔,電路基板穿過穿孔而夾設於彈性束縛體與受測部位之間,訊號蒐集元件接觸該受測部位皮膚,該生理訊號量測設備導接電連接器且控制訊號蒐集元件運作而取得生理訊號。3...探頭31...電路基板310...通孔32...電連接器331...電訊號感測電極332...紅光二極體333...近紅外光二極體334...感光二極體
