Hi..
I have developed a hand held battery operated low power ECG unit that operates on 3.3V and sends all the Leads data to a mobile through bluetooth. The ECG report is generated onto the mobile (PNG format) which can be send to the expert immediately through MMS in case of emergency. This is basically for the rural areas where the availibility of good doctors are limited.
The problem is that during transportation sometime the switch gets ON and all the battery drains off. For this I need some ON/OFF mechanism like we have in mobile where one has to press and hold the power button for 2-3 seconds in order to ON/OFF the mobile.
Kindly suggest....
