Have you come across https://en.wikipedia.org/wiki/Quartz_crystal_microbalance https://en.wikipedia.org/wiki/Quartz_crystal_microbalance re. the piezoelectric effect, you can apparently measure very small masses.
(It sounds like you do need to apply an alternating current for this though)
- antirez 2y agoCool. Yep, piezos only produce current while the mechanical stress changes its shape, but if the load is stable, no current is performed, so I guess that's the reason why you need to apply an alternating current to it in order to use it that way. Thanks.
