As for connecting sensors to the phone, your best bet will be USB based sensors. Almost the entire sensor market has gone over to these devices because of their easy connection to PCs. The only hitch will be getting access to the hardware I/O specifications of the sensor so you can talk to it. Most sensor companies provide ready-made software and don't publish the I/O specs. You'll need to find one who is willing to work with you. The good news is that there are many of them out there and they are hungry to get their hardware into new applications.
As for the specific sensor, you need to get a physicist involved in your project. The human body is mostly water and the penetration of radio waves is inversely related to frequency. This is well studied and will tell you which bands are going to concern your system. The good news is that low frequencies (the most penetrating) are easy to demodulate with modern high speed A/D systems (like the ones you will have in your USB sensor). You need to get a signal processing expert to help you with that part but modern Android phones have enough processing power to handle the task, as I've found in my own work. You'll also need some analog electronics for the "front end" to boost the signal enough to demodulate it. Get an electrical engineer to help you with that. Overall it sounds like a fun project. In general, I recommend consulting experts whenever you can rather than stumbling around. Most are very generous with their time when helping students. Good luck, and let me know if you get the system working well enough for a demo. I know a huge number of venture capitalists who are always on the lookout for investment opportunities. -- You received this message because you are subscribed to the Google Groups "Android Beginners" group.
