Abstract
The invention relates to an electronic sensor for detecting skin, the sensor comprising processor, an EM source, a baffle, a first EM detector and a second EM detector, the sensor arranged such that the EM source is located on a first side of the baffle and the first and second EM detectors are arranged on a second opposite side of the baffle at first and second distances from the EM source respectively, the first distance being less than the second distance, the processor configured to cause the source to emit EM radiation and to receive first and second signals from the first and second EM detectors respectively, the signals being indicative of the intensity of EM radiation detected by the sensor, the processor being further configured to process the first and second signals and thereby generate a skin signal which is indicative of whether the sensor has detected skin.
