Abstract
The present invention is related to a contact detection device () for detecting a contact between the contact detection device () and an object (), a method (), a diagnostic device and further to a computer program. The invention seeks to improve the reliability of contact sensors. The contact detection device () comprises a heater () for providing a modulated heat flow (). A modulated heat signal () is generated in dependence of the modulated heat flow (). A physical contact with an object () causes a change in the modulated heat flow () that effects the modulated heat signal (). As the heat flow is modulated, a change in the modulated heat signal () is quasi assured. A contact determination unit () of the contact detection device () derives a contact indication signal () indicating at least either the presence or the absence of the physical contact in from the modulated heat (), preferentially by means of a demodulator ().
