A kind of heart beat detection band a, comprising: ontology is equipped with a first electrode sheet and a second electrode sheet, and what ontology lower surface is arranged in first electrode sheet, and second electrode sheet is arranged on any surface of the non-lower surface of what ontology； One processing mould group, is arranged in what ontology, is respectively coupled to first electrode sheet and second electrode sheet； One sensor, setting what ontology is interior and couples processing mould group； And a shoestring, in conjunction with ontology, to by the fixed what human body of ontology. The utility model heart beat detection band carries out measurement posture in user and close or touch sensor Hou can automatically turn on heart beat detection band, and what measured Hou and is automatically closed, fluent movements and saving power supply when using.一種心跳偵測帶，包括：一本體，設有一第一電極片及一第二電極片，第一電極片設置於本體下表面，第二電極片設置於本體之非下表面的任一表面上；一處理模組，設置於本體內，分別耦接第一電極片及第二電極片；一感測器，設置於本體內並耦接處理模組；及一帶狀體，與本體結合，用以將本體固定於人體。本新型心跳偵測帶在使用者做好量測姿勢並靠近或觸碰感測器後即能夠自動開啟心跳偵測帶，並於量測過後自動關閉，其使用時動作流暢且節省電源。
