The sensor may be a capacity sensor; one or two webs being located at a suitable place and comprising a conductive net; or a bag comprising air or a fluid.
The actuating means is, for example, an electronic circuit comprising a frequency oscillator; a unit which switches the oscillator on periodically; and a unit which switches the receiver on and off, which consists of a key and an optoisolator.
The pillow case advantageously comprises the story to be told.
