An integrated vibrations and contact force converter, comprising: a first element (11) separated from a second element (12) by an elastic spacer (170)； at least one acceleration sensor (116) configured to measure amplitude of acceleration of vibrations of the converter； at least one contact force sensitive element (151, 152, 183) configured to measure the force exerted on the second element (12)； wherein the first element (11) and the second element (12) are connected by a connector (16) configured to provide a non-zero pressing force from the first element (11) to the second element (12) at the absence of forces external to the converter.
