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 readings from breathing and temperature. The sensors transmit health data via zigbee to a microcontroller in the phone. This allows patients to monitor their health, get alerts, and understand their conditions without a physician. Multiple patients can form a wireless network connected to local hospitals, allowing medical staff to remotely monitor patients and send help if readings are abnormal. Location tracking is also possible using GPRS.
