ok, beside marketing or not :
the "sensor" might be a simple cap, ceramics like Z5U have piezo effects, or a piezo-sensor (?);
if there is a shot in the mosfets, probably a ultra-sonic noise is generated, and with a sensor for "mechanical" noise this could be measured.
>> ever heard a triac switching? with every current pulse ( = swiching on ) a "tick" can be heard, so this could be the same in mosfet at high current.
could you measure the cap aka "sensor" ?
