HAPTIC™ Reactor

The HAPTIC™ Reactor is an electromagnetic actuator that makes use of the interaction between a magnet and coil. The device efficiently harnesses the resonance phenomenon in the springs of an oscillator to generate vibrations.

With an ERM motor, rotation speed increases with the input voltage, making vibrations bigger and the frequency higher. With a HAPTIC™ Reactor, vibration strength and frequency can be controlled separately according to the input. This makes it possible to produce various sensations.

The Hybrid Tough Type has been used for a number of VR and AR controller applications.
The Heavy Type has been used for a number of automotive control feedback applications.

When holding it in your hands, you will probably not be able to distinguish the direction of vibration.

Sensory receptors in human fingertips tend to falsely perceive horizontal displacement as unevenness, meaning horizontal vibrations can be used to simulate the sensations of a mechanical switch.

Excitation force is evaluated by measuring acceleration with an accelerometer, the product being attached to a suspended 100g block to prevent external influence.

We recommend affixing the Hybrid Tough Type with double-sided tape and the Heavy Type with double-sided tape and screws.
Also consider using a holding structure as required to prevent the product from falling off.

The vibration acceleration of a HAPTIC™ Reactor across a range of input frequencies plots a mountain curve. The peak of the curve (the frequency at which vibration acceleration is largest) represents its resonant frequency.
The Heavy Type has one peak, while the Hybrid Tough Type has two peaks because it has two resonance points.
