A Multimodal Distributed Sensing Device
Tech ID: 34252 / UC Case 2025-457-0
Abstract
Researchers at the University of California, Davis have
developed tactile feedback systems that enhance spatial and sensory resolution
in sensor arrays through unique signal modulation techniques.
Full Description
The technology introduces systems,
methods, and media for implementing sensor arrays that mimic the high spatial
and sensory resolution of human skin. By utilizing unique modulations for each
sensor signal, it allows for dense arrays on a single communication medium,
overcoming the scalability and complexity challenges of conventional sensor
networks.
Applications
- Robotic systems, particularly for tactile sensing in robotic
limbs and end-effectors.
- Healthcare devices, including therapeutic
devices and patient monitoring systems for pressure distribution and ulcer
prevention.
- Industrial automation, for monitoring contact
forces and surface interactions.
- Wearable technology, for sensing physical
parameters such as pressure and temperature.
- Prosthetic devices, enhancing functionality through
high-resolution tactile feedback.
Features/Benefits
- Achieves high spatial resolution with dense sensor arrays,
accommodating up to 100 sensors per square centimeter.
- Reduces system complexity and cost by
eliminating the need for individual wiring and data acquisition channels for
each sensor.
- Implements flexibility on various mediums,
including fabrics and both flexible and rigid PCBs.
- Integrates multiple types of sensors, such as
pressure, temperature, and vibration sensors, within the same array.
- Enables real-time responsiveness through
efficient modulation techniques, allowing simultaneous transmission of multiple
sensor signals.
- Addresses scalability issues of traditional
sensor networks with high-density sensor requirements.
- Overcomes limitations in achieving high spatial
resolution over large areas with existing sensor technologies.
- Solves challenges in integrating diverse sensor types within
a single array efficiently.
