Force sensor for use in bed for determining weight change of sick person during monitoring of rotation of person, has force-sensitive sensor element elevatedly arranged at side of plate, where force to be detected is exerted at another side

摘要

The sensor (1) has a force-sensitive sensor element (3) i.e. force-dependent resistor, elevatedly arranged at a side of a deformation-resistant plate (2), where force to be detected is exerted at another side of the plate according to the use of the sensor. The former side of the plate is divided into different sections, and the sensor element is attached to one of the sections. The force exerted at the latter side of the plate is determined by a measuring result of the sensor element, where the measuring result is outputted by a Bluetoothconnection. An independent claim is also included for a method for operating an arrangement of a couch device and a force sensor.
