Hello All, I am trying to figure out how to power a micropump system that requires 100 volts. I looked at some current micro batteries, and their voltages range between 2 - 4 volts. I am confused on how to provide enough power. Do I just use several batteries in series or use a voltage multiplier or both? Is there a more efficient way to power this type of device? The system I am trying to create is similar in dimension to a pacemaker.
