Cambridge Scientists Unveil a Controllable “Extra Thumb” for Enhanced Hand Function
In a breakthrough that could reshape how we use our hands, researchers at the University of Cambridge have engineered a robotic third thumb that people can control with their feet. The prosthetic aims to increase manual dexterity in everyday tasks and specialized professions such as surgery.
What the Device Can Do
- Carry several glasses or objects at once without sacrificing grip strength.
- Shuffle playing cards quickly and accurately.
- Assist surgeons by adding an additional manipulative point while they juggle instruments.
“A New Era of Productivity”
Tamar Makin, professor of cognitive neuroscience at Cambridge, said, “We’re excited about using this thumb to boost productivity, especially for jobs that demand fine manual control.” She added, “From screen‑writers handling complex scripts to surgeons coordinating multiple tools, the extra thumb could become indispensable.”
Real‑World Testing at the Royal Society Summer Exhibition
During the 2022 Summer Science Exhibition, almost 600 visitors interacted with the prototype. Only four participants struggled to use it—either because the fit was insecure or they couldn’t master foot‑based control. The team noted that pressure‑sensing pads originally designed for the exhibition were too heavy for some young users.
Performance Outcomes
The research, published in Science Robotics in May, reported that 98% of users succeeded in manipulating objects with the extra thumb within the first minute of experience. Importantly, the study found no meaningful differences based on gender, handedness, or hobby preferences.
Looking Ahead
With further refinement, the autonomous robotic thumb could become a standard tool in both industrial settings and medical environments, enabling humans to perform tasks with greater speed and precision.
How does it work?
Reimagining Dexterity: The Emergence of a Digital Third Thumb
The latest breakthrough in wearable robotics places the spotlight on a device that adds an extra digit for users—an artificial third thumb that promises to transform both everyday interactions and specialized skill sets.
Designed Specifically for the Skilled Hand
Lead researcher Dr. Makin emphasizes that this technology was built with the human hand in mind. “Our device is crafted for individuals with two fully functional hands, five fingers each, to expand what they can accomplish,” he explains.
He adds, “We want to transcend the inherent physical limits and offer a completely new means of engaging with our surroundings.”
Foot‑Powered Control System
- Pressure sensors beneath each big toe translate foot pressure into thumb movement.
- Pressing the right toe launches the thumb outward across the hand.
- Applying force on the left toe lifts the thumb toward the primary fingers.
- The range of motion is directly proportional to the intensity of the foot’s pressure.
Innovation at Your Footstep
By coupling the device to subtle foot signals, users can manipulate the artificial digit with minimal on‑hand distraction, allowing simultaneous use of their existing fingers.
Ease of Adoption
Developer Dani Clode highlights the device’s user‑friendliness: “We acknowledge that learning any new tool requires practice, but the third thumb feels surprisingly intuitive.”
Clode notes that most users can become proficient within a minute, eliminating the prolonged learning curve associated with many assistive technologies.
Beyond the Able‑bodied
While “designed for the healthy hand,” the research team believes the system could be adapted for individuals with mobility challenges. “We envision scenarios where this thumb offers significant assistance, serving as an alternative to conventional prosthetics,” claims Dr. Makin.
Future Horizons
Ongoing tests aim to uncover the full potential of the third thumb, aiming to redefine human interaction with objects and environments alike.
