Pressure detection and wireless interface for patient bed

A low power, microcontroller based patient bed monitoring system is discussed in this paper. The resistive bend sensor based approach provides an effective low cost alternative for minimizing the harmful effects of bedsores which is prevalent in hospital intensive care units and assisted living environments during rehabilitation. The ZigBee based wireless interface for this pressure detection system is aimed at reducing the hassles of the existing complex wired setup and to provide continuous patient care and monitoring by enabling the patient bed mobility as essentially required for patients in critical condition.
