Piezo Haptic Computer Trackpad with BOS1901 Piezo Driver
Boréas Technologies Product: BOS1901 Piezo Haptic Driver
Application of this module: Computer Trackpad
This haptic computer trackpad module uses the BOS1901 driver with a piezo actuator. This hardware allows thinner, less complex, better performing and less power consuming trackpads than leading haptic trackpad currently on the market.
Piezo actuators can replicate with extremely high fidelity the tactile feeling of using a mechanical clicking trackpad. Our BOS1901 can also sense when force is apply to a piezo actuator, allowing both haptic feedback and force sensing capabilities from the same piezo actuator.
Let's see how the Piezo Haptic Trackpad Module compares to other technologies.
Trackpads with Piezo Haptics are Better
Different computer trackpad technologies comparison. Key advantages of the Piezo Haptic Computer Trackpad:
- Lower Power Consumption
- Thinner Solution
- Better Haptic Feedback
- Simplier Structure
| Characteristics | Traditional Click Pad | Leading LRA Trackpad | Piezo Trackpad |
| Thickness (Touch + Haptics) | 4 mm | 3 mm | <2.8mm |
| Haptic Feedback | No | Yes - LRA (narrow bandwidth) | Yes - Piezo Actuator (wide bandwidth) |
| Force Sensing | N/A | Yes - With additional sensing hardware | Yes - With same Piezo Actuator |
| Response Time | > 50 ms | > 20 ms | < 5 ms |
| Power Consumption | N/A | 60 mW | 5 mW |
| Structure Complexity | Medium | High | Low |
| Weight | 45 g | 65 g | 35 g |
Module Structure
The Piezo Haptic Computer Trackpad Module is less complex thant its mechanical and LRA based counterparts. Using the BOS1901 piezo driver allows force sensing without additionnal hardware, making the integration simplier, more reliable and cost effective.
