TACTILE SENSING DEVICE, AND DETECTION METHOD AND APPARATUS - A simplified explanation of the abstract

This abstract first appeared for US patent application 20240183727 titled 'TACTILE SENSING DEVICE, AND DETECTION METHOD AND APPARATUS

Simplified Explanation

The patent application describes a tactile sensing device that uses optical waveguides to detect contact force.

  • The device includes a light source, optical waveguides, photoelectric sensing components, and a contact point.
  • The light source is located at the input end of each optical waveguide, while the photoelectric sensing component is at the output end.
  • The optical waveguides surround the contact point, with the contact point in contact with each waveguide.
  • When a contact force is applied at the contact point, the optical waveguides deform, causing losses in the transmitted optical signals.
  • The photoelectric sensing component detects the variations in the optical signals to determine the value and direction of the contact force.

Potential Applications: This technology could be used in robotics for tactile feedback systems, medical devices for pressure sensing, and virtual reality applications for enhanced user interaction.

Problems Solved: This technology solves the problem of accurately detecting contact force in a tactile sensing device, allowing for more precise and sensitive touch feedback.

Benefits: The benefits of this technology include improved accuracy in detecting contact force, enhanced tactile feedback in various applications, and increased sensitivity in touch-sensitive devices.

Potential Commercial Applications: Potential commercial applications include the integration of this technology into touchscreens, gaming controllers, medical devices, and industrial robots for improved tactile sensing capabilities.

Possible Prior Art: One possible prior art for this technology could be the use of strain gauges or resistive sensors for detecting contact force, which may not offer the same level of sensitivity and accuracy as the optical waveguide-based system.

Unanswered Questions:

1. How does the device handle variations in contact force intensity?

  - The device can detect variations in contact force intensity by analyzing the changes in optical signals transmitted through the deformed optical waveguides.

2. What is the response time of the device in detecting contact force?

  - The response time of the device in detecting contact force would depend on the speed at which the optical waveguides deform and the photoelectric sensing components analyze the variations in optical signals.
