加速度傳感器中有一種是三軸加速度傳感器，同樣的它是基于加速度的基本原理去實現工作的，加速度是個空間矢量，一方面，要準確了解物體的運動狀態，必須測得其三個坐標軸上的分量；另一方面，在預先不知道物體運動方向的場合下，只有應用三軸加速度傳感器來檢測加速度信號。由于三軸加速度傳感器也是基于重力原理的，因此用三軸加速度傳感器可以實現雙軸正負90度或雙軸0-360度的傾角，通過校正后期精度要高于雙軸加速度傳感器大于測量角度為60度的情況。三軸加速度傳感器的好處就是在預先不知道物體運動方向的場合下，只有應用三維加速度傳感器來檢測加速度信號。三維加速度傳感器具有體積小和重量輕特點，可以測量空間加速度，能夠全面準確反映物體的運動性質。
美國Dytran的3023A1是一款微型三軸加速度傳感器/振動傳感器，壓電式工作原理，重量4g，自帶4針徑向連接器和5-40鉸軸安裝設計，同時集成3個石英剪切感應元件，再配備鈦合金外殼，應對超高濕度和多塵工作環境。
The Dytran 3023A1 is a miniature triaxial IEPE accelerometer weighing just 4 grams.
