5 FAQ About HapticTouch

1. How many haptic piezo actuators can be controlled by a single Aito®Chip?

Our Aito®Chips control up to 8 piezo discs. All of the piezo discs can be configured and controlled individually. 


2. What kind of haptic effects can the Aito®Chip provide? 

Most of our customers are looking for haptic feedback that enhances user interface operations such as clicking or sliding. We are also planning for a broader range of effects, including feeling texture, roughness or stiffness. 

For example, we’ve made a solid, cube-shaped object feel like a sponge when squeezing it between your fingers.


3. How does Aito®HapticTouch cope with very stiff materials, for example, an illuminated control panel in a car dashboard?

By controlling and driving several piezo discs at the same time in parallel, we can actuate an entire surface at once. As long as the dashboard construction allows for free movement of your surface, our Aito®Chip can add haptic feedback to very stiff materials without limitations. 

Keep in mind that for fast and responsive haptic feedback, the weight of the control surface should be as light as possible, as mass inertia will lower the haptic sensation and may increase unwanted audio noise.


4. Can the Aito®Chip be implemented with touch solutions such as capacitive sensing or optical sensing technologies?

Yes! This is very simple. With our Aito® Design Studio tool, you can set up and configure the Aito®Chip and determine exactly what kind of haptic feedback you want to achieve and control all parameters such as timing and force.


5. Does Aito®HapticTouch drain the power of my battery-operated device?

Not at all. Our Aito®Chip has been developed with energy efficiency in mind. A typical haptic feedback pulse uses 0.7 mJ, which is good for more than 3 million haptic feedback cycles when using the energy from a small CR2032 coin cell battery.
