REQUIREMENT
Requirement
- Tactile sensation similar to a mechanical button
- Compatibility with capacitive touch sensors
- No influence in the field of vision
- Easy integration into existing systems
- Compact design and low energy consumption
- Robust construction without moving parts, simple and reliable sealing
Solutions
- Patented method: jerky bending of the front panel when reaching a defined pressure point
- Recording the contact force (= pressure point) by measuring the strain in the edge area
- Active deformation of the plate by two-dimensional piezo actuators (placement also in the edge area)
