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 |
