Wearable haptic skin strain system

A wearable haptic system utilizes a hook and eye architecture to enable rapid attachment and detachment of skin strain actuators.
Technology No. 2023-241
IP Status: PCT Pending; PCT No. PCT/US2024/022489

Applications

  • Virtual and augmented reality haptics
  • Notification systems
  • Touch sensitivity assessment
  • Personalized haptic feedback

Key Benefits & Differentiators

  • Easily repairable and scalable: A unique hook and eye architecture allows for simple removal and replacement of individual actuators.
  • Increased user comfort: The system uses a silicone backing to provide skin strain without relying on uncomfortable and painful skin adhesion.
  • Enhanced perceptibility: The hook and eye design holds actuators closer to the garment's surface, improving the user's perception of the haptic feedback while preventing snagging.
  • Benefit: Features that provide the benefit

Technology Overview

The sense of touch is a primary way people interact with their environment, with skin strain being a key component of this experience. Haptic technologies aim to replicate this sense, but existing wearable skin strain systems often face challenges related to comfort and practicality. Many systems permanently attach actuators, making them difficult to repair and scale. Others rely on uncomfortable methods like skin adhesion, which can cause pain and irritation upon removal. These shortcomings hinder the widespread adoption and commercial viability of wearable haptic devices.

Researchers at the University of Minnesota have developed a wearable haptic skin strain system that addresses these limitations through a novel hook and eye architecture. This design allows for the rapid and easy removal or replacement of actuators, improving the system's repairability and scalability. Unlike solutions that rely on skin adhesion, this system uses a silicone backing to comfortably produce skin strain without sticking to the skin. By holding the actuators closer to the garment surface, this unique design also enhances the user's perception of the haptic feedback while preventing snagging, offering a more comfortable, practical, and effective solution for wearable haptics.
