The term originated with mechanical timepieces, whose clockwork movements are made of
Insides of a slip-stick piezoelectric motor. Two piezoelectric crystals are visible that provide the mechanical torque. [1]A piezoelectric motor or piezo motor is a type of electric motor based on the change in shape of a piezoelectric material when an electric field is applied, as a consequence of the converse piezoelectric effect.
Grasshopper escapement, 1820. The grasshopper escapement is a low-friction escapement for pendulum clocks invented by British clockmaker John Harrison around 1722. An escapement, part of every mechanical clock, is the mechanism that gives the clock's pendulum periodic pushes to keep it swinging, and each swing releases the clock's gears to move forward by a fixed amount, thus moving the hands ...
