Improving the reliability of pressure ulcer prevention by sensing human bio-signals: Analysis of using piezoelectric sensors to sense respiration and heart rate

Pressure ulcers, also known as bedsores, are wounds that form when a person sits or lays in the same<br/>posture for an extended period of time. Continued pressure being applied to the same spot causes<br/>the skin to decay, possibly continuing into underlaying tissue if the wounds are not treated.
