Piezoelectric effect is when certain solid material is compressed under mechanical stress, and it develops a voltage potential by accumulating electrical charges. French physicists Jacques and Pierre ...
Fig 1. The MEMS pressure sensor detects the tensile stress on a thin silicon membrane that changes the piezo-resistance of elements on the membrane’s surface. Fig 2. The MEMS sensor’s piezo-resistive ...
A designer and a senior engineer analyze a low-cost alternative for solid-state general-purpose impact sensing uses a standard piezoelectric device (PZT) an a 555 timer. When the piezoelectric device ...
