Only if it runs on a a few microwatts (average power consumption). Any buffering to normal timescale batteries or large capacitors would introduce additional losses. Their self discharge rate might even exceed the power output of such a battery. I get it. It's a joke, but given that those devices are supposed to be worn on the body several energy recovery options exist that far exceed the power you can expect to get from an isotope battery in a compact device before the blue effects come from Cherenkov radiation instead of CGI and require frequent user changes instead of battery changes. Unless you have a copy of APOLLO stowed away changing batteries is easier than training new users ;-).
