Patient off-bed notification system

A patient off-bed notification system, comprising:

• a pressure-sensitive sensor pad, comprising an upper conductive layer, a bottom conductive layer and an insulating layer arranged therebetween, wherein the insulating layer comprises a set of pierced regions that partition the pressure-sensitive sensor pad into a plurality of pressure-sensitive sensing zones, wherein the upper conductive layer and the bottom conductive layer is configured to generate an electrical signal due to pressure change at one or more of the plurality of pressure-sensitive sensing zones;
• a signal converter, electrically connected to the pressure-sensitive sensor pad, wherein at least two different pressure-sensing zones of the plurality of pressure-sensing zones generate at least two different electrical signals to the signal converter, wherein the signal converter receives the electrical signals sent by the pressure-sensitive sensor pad and performs operational analysis to produce a corresponding patient status signal, wherein producing the patient status signal comprises (i) identifying, based on the electrical signals, one or more pressure-sensitive sensing zones experiencing the pressure change, (ii) mapping the identified pressure-sensitive sensing zones to a patient status selected from a plurality of defined patient statuses;
• and
• a signal transmitter, electrically connected to the signal converter, and used to transmit the patient status signal from the signal converter.
