IOT is a current trending technology which access electronic components through internet .In this paper, various sensor nodes can be placed on different positions of the body to measure the subject’s body temperature distribution, heartbeat and detect falls. To extend the lifetime of the wearable sensor node, a flexible solar energy harvester with an output based maximum power point tracking (MPPT) technique is used to power the sensor node. The system with solar energy harvesting demonstrates that long-term continuous medical monitoring is possible. There are various energy harvesting techniques available from that solar energy harvesting is used to extract energy and send it to the rechargeable battery. By using rechargeable battery with energy harvesting technique long term 24 hours autonomous medical health monitoring is possible.
