The present invention provides a capacitive accelerometer device including a capacitive accelerometer module, a display device and a signal line. The capacitive accelerometer module includes one or more capacitive accelerometers for sensing an artery acceleration pulse wave of a user. The display device includes a displayer and a speaker. The displayer used to display the artery acceleration pulse wave of the user. The speaker emits an audible signal according to a changing value of the artery acceleration pulse wave. The display device electrically connected to the condenser accelerometer via the signal line. The display device automatically senses the artery acceleration pulse wave of the user and generates the changing value. The display device generates a prompt signal when the changing value is equal to or over than a predetermined value.本發明提供一種電容式加速度計裝置，包括電容式加速度計模組、顯示裝置及信號線。電容式加速度計模組具有一個或多個電容式加速度計，用於以接觸方式感測使用者的動脈加速度脈波。顯示裝置具有顯示螢幕及揚聲器，顯示螢幕用於顯示使用者的動脈加速度脈波，揚聲器根據動脈加速度脈波的變化值發出聲音信號。顯示裝置通過信號線電性連接電容式加速度計模組。顯示裝置自動偵測使用者的動脈加速度脈波並相對產生變化值，當變化值等於或超過預設值時，顯示裝置產生警示信號。
