HAPTIC FEEDBACK BASE PLATE, HAPTIC FEEDBACK APPARATUS AND HAPTIC FEEDBACK METHOD - A simplified explanation of the abstract
This abstract first appeared for US patent application 17620538 titled 'HAPTIC FEEDBACK BASE PLATE, HAPTIC FEEDBACK APPARATUS AND HAPTIC FEEDBACK METHOD
Simplified Explanation
The present disclosure describes a haptic feedback base plate, apparatus, and method for providing haptic feedback.
- The haptic feedback base plate includes a substrate and a deformation unit on one side of the substrate.
- The deformation unit consists of a first electrode, a piezoelectric material layer, and a second electrode arranged in a stacked manner.
- The first electrode is positioned close to the substrate, and the first and second electrodes create an alternating electric field.
- The piezoelectric material layer vibrates due to the alternating electric field and causes the substrate to resonate.
- The frequency of the alternating electric field is set to be within a certain threshold of the inherent frequency of the substrate.
Potential applications of this technology:
- Haptic feedback in touchscreens and touchpads to enhance user interaction and provide tactile sensations.
- Gaming controllers and virtual reality devices to simulate physical sensations and improve immersion.
- Medical devices and surgical simulators to provide realistic haptic feedback during training and procedures.
Problems solved by this technology:
- Provides a simplified and efficient way to generate haptic feedback by utilizing the resonance of the substrate.
- Overcomes the limitations of traditional haptic feedback methods that require complex mechanisms or actuators.
- Ensures that the frequency of the alternating electric field is within a specific range to prevent damage to the substrate.
Benefits of this technology:
- Offers a compact and lightweight solution for integrating haptic feedback into various devices.
- Provides a more realistic and immersive user experience by adding tactile sensations.
- Reduces the complexity and cost of implementing haptic feedback in electronic devices.
Original Abstract Submitted
The present disclosure provides a haptic feedback base plate, a haptic feedback apparatus and a haptic feedback method. The haptic feedback base plate comprises: a substrate and a deformation unit disposed on one side of the substrate. The deformation unit comprises a first electrode, a piezoelectric material layer and a second electrode that are arranged in a stacked manner, the first electrode is arranged close to the substrate, the first electrode and the second electrode are configured to form an alternating electric field, and the piezoelectric material layer vibrates under the effect of the alternating electric field and drives the substrate to resonate, wherein a difference between a frequency of the alternating electric field and an inherent frequency of the substrate is less than or equal to a preset threshold.
