Hi George

I've always used triboelectric,

tribo as in to rub since the study of lubricants is tribology

Checking with Google there are 3000+ references to triboelectric and

1 entry for piezophoto and 1 for piezophotic

although I admit that light emission from wintergreen candy does stem from
piezoelectric sparks exciting the fluorescent light output from oil of
wintergreen. So piezophotic sounds correct.
