Abstract
An electric field mattress and a method for monitoring movement of a person are disclosed. The electric field mattress comprises a plurality of electrodes, a waveform generator electrically coupled to the electrodes for generating an electric field, and a detector coupled to at least one of the electrodes for detecting variations in the electric field. Variations in the electric field are caused by movement of a subject in the electric field.
