On the design and development of a Zigbee-based multimodal input-output monitoring-actuating system

An affordable and expandable monitoring and actuating system is beneficial to medical professionals for dealing with the needs of patients. Technically, the design and development of a multimodal-input and output monitoring and actuating wireless system is discussed. The circuitries and interfaces of touch and tilt sensors at the input and actuating parts at the output (voice, vibration and light) are discussed. It is shown how to set up a small wireless network using 3 XBee series 1 Zigbee modules using application programming interface. Compared to many monitoring systems, this system has an actuating capability. The hardware and the software parts are designed and integrated in such a way that a new sensor at the input or a new actuator at the output can be included or excluded based on the needs of the patient. The prototype of the system was tested with promising results in the case of the patients with inattention disorder.
