Vibration waveform sensor and waveform analysis device for continuously measuring and analyzing the acceleration waveform of vibration while keeping the power consumption low
The object of the present invention is to continuously measure and analyze the acceleration waveform of vibration while keeping the power consumption low. In the present invention, a sensor module 10 is provided with a structure having a vibration ring 40 adopted to cover a piezoelectric element 30 placed on the principal face of a substrate 20, and is installed in an appropriate position on the arm, neck and the like of a human body by using a medical fixing tape and the like in a manner that the vibration ring 40 abuts against the skin BD of the human body. If a pulse wave is transmitted from the skin to the vibration ring 40 for vibrating the substrate 20, this vibration is transmitted to the piezoelectric element 30. Therefore, the piezoelectric element 30 is displaced and the vibration of the pulse wave is converted to an electrical signal. The electrical signal is amplified by an amplifier on the substrate 20 and inputted to a vibration analysis device 100, where a specific calculation is executed to perform waveform analysis, so that the vascular state and the like can be known from the pulse waveform.本發明之課題係以低消耗電力連續地測定振動之加速度波形且進行解析。 本發明之感測器模組10係採用以振動環40覆蓋配置於基板20之主面上之壓電元件30之構造,且於人體之手腕或頸部等之適當位置,藉由醫療用之固定膠帶等,將振動環40以抵著人體之皮膚BD之方式安裝。若脈波自皮膚傳至振動環40,會進而振動基板20,而將其傳達至壓電元件30。於是,壓電元件30位移,將脈波之振動轉換為電性信號。將該信號藉由基板20之放大器放大而輸入至振動解析裝置100,進行特定之運算而進行波形解析。可自脈之波形獲知血管之狀態等。10‧‧‧感測器模組20‧‧‧基板22‧‧‧電極焊盤22A‧‧‧通孔23‧‧‧電極焊盤23A‧‧‧通孔24‧‧‧接地導體24A‧‧‧通孔24B‧‧‧通孔30‧‧‧壓電元件40‧‧‧振動環41‧‧‧腔室
