> internal battery to give you 30-60s you meant a super condensator, right?

  Supercap or battery: anything with a decent enough density to give you enough time to swap the battery without losing state or being stressed out.

    A cap like that might not fit.

      Maybe .. another battery? One with 5-10% the size and capacity of the main one? Although in both cases the power management is a little tricky.

      Capacitors can be made in a variety of shapes, internally they're a simple sandwich-like structure of a couple different types of material: https://upload.wikimedia.org/wikipedia/commons/thumb/3/35/Parallel_plate_capacitor.svg/2000px-Parallel_plate_capacitor.svg.png https://upload.wikimedia.org/wikipedia/commons/thumb/3/35/Pa... Capacitors are usually cylindrical to increase the available surface area whilst keeping the horizontal size down ( http://www.camion.com.tw/images/en_basic_structure.gif http://www.camion.com.tw/images/en_basic_structure.gif ), but they don't have to be designed this way. Here's an example of a flat supercapacitor: http://gpsworld.com/cap-xx-launches-0-6mm-thinline-supercapacitors-for-wearables/ http://gpsworld.com/cap-xx-launches-0-6mm-thinline-supercapa...
