The sensor has two sheets (18, 20) of polarized polymeric piezoelectric material secured together with their main uniaxial mode aligned with axis (16). These are connected to an electric oscillator to induce mechanical oscillation of the assembly (10). A third sheet (22) of like material is secured to the sheets (18, 20) but has its main uniaxial mode transverse to the axis (16). Twisting of the assembly due to rotational acceleration causes substantial alteration of the voltage induced in the third sheet (22), the voltage being proportional to the rate of rotational acceleration. |
