Piezoelectric microphones work by converting mechanical vibrations (sound waves) into electrical signals. When sound waves hit the piezoelectric material in the microphone, it generates tiny electrical charges proportional to the sound pressure. These electrical signals are then amplified and processed to produce audio recordings or for use in communication systems.

The piezoelectric microphone was invented in 1917 by Aleksandr W. Gurvich and his colleagues. They discovered the piezoelectric effect in Rochelle salt crystals, leading to the development of the first piezoelectric microphone.
Many piezoelectric crystals can be used in water with no issues.
No
Yes they have to be wired correctly. All the injectors do not run at the same time. They only work when needed to supply fuel to a cylinder on the compression stroke.
There was a recall on the fuel injectors on the M30's due to leakage. Just take it to a dealer and they will replace the injectors for free. You'll even get a loaner car while they work on yours.
Ur car doesn't work
No, the injectors are rated differently, you would be dumping fuel into the engine. The computer and injectors wouldn't match up.
Yes, gypsum is piezoelectric. This means that it can generate an electrical charge when mechanical stress is applied to it, such as pressure or squeezing.
yes - but they have to be top feed injectors. you can also get low and high impedence injectors, i cant rember which the RX7 uses but it has to be the same impedence. CC can change to suit the desired amount of fuel. cheers.
yes
