Install piezoelectric discs on your acoustic guitar soundboard to harvest vibration energy, collected in a small battery. The power collected from strumming the instrument can be used to power an onboard digital tuner.

       Could work, though one would have to take note of where the energy is being harvested, lest it affect the sound.   

       It would make sense to include this function on a self-tuning guitar [link].
