<p>PROBLEM TO BE SOLVED: To provide a measurement device capable of measuring a force exerted from outside with higher sensitivity.SOLUTION: A measurement device includes: a force sensor 14A that is deformed by a periodical force exerted from outside to output a change in a resistance value based on a deformation state as a measurement signal; a reference signal output unit 16 for outputting position information of the force sensor 14A that is displaced periodically as a reference signal; and a synchronous detector 50A into which the measurement signal and the reference signal are input and which outputs a signal of a predetermined frequency.</p> |
