Abstract
A detection system for a handle of a car access assembly that includes a sensing module and a flexible printed circuit board. The sensing module includes at least one strain gauge having a sensing area and connection points in contact with the sensing area so as to permit the measurement of a signal at the connection points. The flexible printed circuit board has a first end with at least one connection area adapted to be connected to the connection points of the at least one strain gauge and a second end with a connection arrangement configured to be connected to an electronic control unit.
