## Technologies {#technologies}
|
||||
|
||||
There are two main technique for force sensors:
|
||||
|
||||
- piezoelectric technology
|
||||
- strain gauge technology
|
||||
|
||||
The choice between the two is usually based on whether the measurement is static (strain gauge) or dynamics (piezoelectric).
|
||||
|
||||
Main differences between the two are shown in Figure [1](#orgc54ca38).
