Conclusion
With the basics of powering external devices and communicating with them now in place, it will soon be possible to
plug a small circuit board into almost any existing mobile phone, power an external sensor (e.g. EKG, PulseOx,
etc.), bias it with a voltage, read its analog output back, perform some sophisticated filtering, and present an instant
result. In short, a parasitically-powered analog expansion interface for the mobile phone will enable many new
applications that are either impossible or infeasible with today’s technology.
