Mobile phones can be used to monitor human health using wireless nano sensors and an embedded system. Nano sensors placed in mobile phones can detect minute variations in the body to monitor conditions like asthma, cancer, blood pressure, and ECG. The sensors transmit health data via zigbee to a microcontroller in the phone. This allows patients to monitor their health, get alerts, display their condition and causes without a physician. Multiple patients can form a wireless network connected to local hospitals for remote health monitoring and emergency response if needed. Location is also trackable using GPRS.
