Abstract: A force sensor in the integral/monolithic comprises a monolithic block of elastic material which includes a first, second and third plate; a first pair of leaf spring integrally interconnecting the first and second plate, so that the first and second plates can parallely vibrate relative to each other in a first direction; a second pair of leaf springs integrally interconnecting the first and the third plates so that the first and the third plates can parallely vibrate relative to each other in a second direction being at right angles to the first direction; a shaft clearing traverses a bore in the first plate and is affixed to the second plate; the third plate is provided for connection for force receiving; and strain gauges are placed on all the leaf springs to sense separately forces acting in the first and second directions.
