Abstract
The invention relates to a heatable touch sensor and a steering wheel. It has an optical waveguide which is connected to an electrical heat conductor. The optical waveguide changes its transmission behavior, which is determined, with a change in position or bending. The heat conductor is a resistance heater which emits heat by applying an electrical voltage and by the associated current flow. The touch sensor operates by means of optical interferometry, which enables a very high sensing accuracy.
