Undercover superwoman error

A young looking superwoman is making a basic error pretending to be a electronic rework tech.   She's enjoying the gentle warmth of the soldering iron forgetting a normal human would have a badly burned hand.   She's too distracted producing invisible particle beams to power up and test the circuit board and watching the electrical outputs.   For her this is relaxing like a human might play an piano.   At the same time another super sense lets her feel the life energy all around: microorganisms floating in the air and on the surfaces, the nearest humans drinking coffee.
