Wireless hydrotherapy smart-suit network for posture monitoring
| Resumo: | A wireless smart-suit network for monitoring body kinetics, heart and respiratory rate during hidrocinesiotherapy sessions is presented. Sensing modules composed by 3-axis accelerometers, 3-axis magnetometers and interface electronics are used to monitor the body kinetics. Heart rate is measured using an ear clip infrared sensor and respiratory frequency is measured with inductance plethysmography. The sensor network is integrated in a swimming suit and data is transmitted in real time to a base station using a 2.4 GHz RF transceiver. Measurements of the rotation of shoulders, hips and spine are performed with a resolution of less than 2 degrees. A new MAC protocol for wireless sensing and actuation, LPRT protocol, implemented in MICAz motes is used. Some of the characteristics of the proposed protocol are low power consumption, real-time support and loss intolerant traffic. The protocol uses contentionfree operation and retransmission scheme and is very flexible and has high throughput efficiency. |
