Question

When a pressure is applied to a capacitive transducer that is composed of quartz diaphragms as its plates, a
deflection is obtained. Given that the diaphragms have an area of 900mm² and they are initially 4mm apart
with a capacitance of 390pF. Find the deflection if a pressure of 1400kN/m² results in a capacitance of
480pF.

In many keyboards, the key switches are built as air-filled parallel-plate capacitors with a spacing that decreases when the key is pressed. This change in spacing increases the capacitance, which connected circuitry registers as a keypress. Suppose the plate area on a key is 44.8 mm2 and the unpressed plate separation is 0.63 mm. If the circuitry registers a keypress when the capacitance changes by 0.476 pF, calculate the distance (in mm) the key must travel to register a keypress.
