Development of an Internet of Things System for Measuring the Direction of Use of Body Pressure Dispersion Cushions using Radio Frequency Identifier

摘要

Pressure ulcer prevention guidelines recommend repositioning within 4 hours. For encouraging implementation, IoT technology was used to design a pressure distribution cushion with an embedded radio frequency identifier (RFID) tag and a prototype Android smartphone application to read the tag. As a result of the RFID tag reading experiment, 83% without blanket and 13% with blanket could read the correct posture successfully. In addition, the position was correctly read by the system. With this prototype, the body position could be detected appropriately.
