Abstract
Pressure sensing devices for use with an inflatable bladder and monitoring apparatus for an at rest subject are disclosed herein. The device can comprise a housing comprising a recess and configured to be welded in a seam of the inflatable bladder. A pressure sensor can be located within the recess with a sensing side configured to be exposed to the cavity of the inflatable bladder and a reference side configured to be exposed to ambient air. A printed circuit board can be located within the recess and coupled to the pressure sensor. The pressure sensor is operable to detect a pressure change within the cavity due to a force exerted by a subject on the inflatable bladder.
