You don't, except perhaps via custom firmware. > If not, does anybody know if the iPhone iOS > can do it? Possibly, but this has nothing whatsoever to do with this list. > Ultimately, I am > wanting to integrate custom medical sensors, like EEG and ECG. Those are not sensors, in Android's use of the term. If you look at SensorManager and related classes, you will notice that neither EEG nor ECG appear there. EEG and ECG have nothing whatsoever to do with the accelerometer, gyroscope, or any of the other standard sensors. > Anybody have ideas how to do that? Use USB, Bluetooth, or WiFi, whichever your "custom medical sensors" support. Or, write your own custom firmware with direct hooks to your hardware (connected via soldering iron, I guess) and your own SDK add-on with an API for accessing said hardware, though this particular subject is out of scope for this list.
