Selecting the Right Type of Power Supply of Mobile Applications

When developing new battery-operated devices, the decision regarding the type of power supply required is often left too late or given too little attention. This is particularly the case today when so many mobile gadgets – or wearables – are in development.

Since its beginnings in around 1780 with the Italian physician Luigi Galvani, the field of electrochemical battery technologies has not developed at the same speed as the semiconductor industry where Moore's law applies.

The fundamental principles of primary and secondary cells have been investigated at length. The central electromotive series are known. This seems to have lulled developers into a false sense of security.
