Furthermore, an energy buffer system is added which backs up and allocates the induced power to allow mouse operation and energy storage to occur in a coordinated way. This system allows the mouse to sustain in operation even when it is moved away from the mouse-pad. A minimum duration of 2 minutes was achieved when the mouse was
It was chosen that supercapacitors added as energy storage should provide additional buffer power for 30 s when the drive is started. To calculate the equivalent capacity of a block consisting of several supercapacitors of its own capacity, the following formula is applied [ 12 ]:
