Tech Enables Robots And Amputees To Feel Touch

Researchers at Uppsala University and Karolinska Institutet have developed an artificial tactile system that could enable robots and prosthetic hands to sense touch as quickly as humans. TechXplore reports that this system mimics the human nervous system’s reaction to touch using electrical pulses.

This technology, inspired by neuroscience, can recognise various objects and surfaces, enhancing the natural and safe interaction between humans and robots or prosthetics. Researchers aim to develop this system further to detect pain, heat, and different materials, making it possible to create a complete artificial skin for robots.

This breakthrough could revolutionise prosthetic functionality and robot interaction, providing human-like touch sensitivity.

How Tech Is Enabling Robots To Feel Touch

ScienceDaily reported that research from Uppsala University and Karolinska Institutet may revolutionise how robots and prosthetic limbs feel touch. Published in the journal Science, this breakthrough could also help restore functionality for stroke patients.

Artificial Tactile System

The artificial tactile system mimics the human nervous system’s response to touch. It uses electrical pulses to process dynamic tactile information, allowing a prosthetic hand to feel like part of the user’s body. Zhibin Zhang from Uppsala University notes that their system can distinguish objects by touch as accurately as a blindfolded person.

The system is made of three main parts:

Electronic Skin (e-skin): Sensors detect pressure by touch.

Artificial Neurons: Convert analogue touch signals into electrical pulses.

The Processor: Processes the signals to identify objects.

In tests, it has recognised 22 different objects and 16 types of surfaces. According to Libo Chen, the technology could eventually differentiate materials like wood and metal and even detect pain and heat.

Applications and Future Development

This technology could improve human-robot interactions, making them safer and more natural by providing tactile feedback. It allows prosthetic hands to handle objects with human-like dexterity. Moreover, e-skin could be produced for entire robots, greatly enhancing their sensory capabilities.

Medically, the system could monitor movement dysfunctions from diseases like Parkinson’s and Alzheimer’s and aid stroke patients in regaining lost functionality. According to Zhang, it might even predict falls, triggering external muscle stimulation or assistive devices to prevent accidents.

This research opens new possibilities for both robotics and medical applications, marking a significant step forward in tactile technology.
