Benefits and drawbacks of piezoelectric, piezoresistive, and capacitive triboelectric sensors.

Sensor type	Benefits	Drawbacks
Piezoelectric	Wide frequency response range; High sensitivity; Simple structure; Cost effective	Dynamic signal only; Leakage of electrical charge
Piezoresistive	Wide response range; Simple structure; High resolution	High temperature errors; Complex manufacturing process
Capacitive	High stability; Good dynamic response	High impedance; Poor load capacity
Triboelectric	High sensitivity; Simple structure; Cost effective	High impedance; Dynamic signal only
