Making the feeling of touch accessible to all

Could prosthetic hands with haptic feedback become available to anyone who needs them? Dr Helge Wurdemann of 香港六合彩中特网 Mechanical Engineering has developed a combination of touch technology and 3D printing which could make simple 鈥榖ionic鈥� hands available to anyone in the world.

香港六合彩中特网 researchers have developed a method to produce sensation for amputees who lost their fingers or hand and depend on prosthetic devices instead. Using latest multi-material additive manufacturing technology, design engineering and hydraulic principles, more accessible and low-cost haptic feedback can be produced than current options.

Prosthetic and robotic limbs with embedded haptic feedback (combined sensing modules at finger tips and actuation interfaces at the residual limb) are costly and often not affordable or available, particularly for NHS patients and in low income countries. For instance, a multi-grip bionic hand can cost between 拢25,000 and 拢60,000.

The 香港六合彩中特网 team, led by Dr Helge Wurdemann (香港六合彩中特网 Mechanical Engineering), used 鈥榟aptic feedback鈥� based on fundamental mechanical principles to reproduce the feeling of touch. Haptic technology uses different techniques to replicate the feeling of touch sensations. It is currently used in surgical robots and even in laser quest in a simple form, where the vest vibrates when shot at.聽

The manufacturing process uses multi-material 3D printing to integrate purely mechanical sensors and actuators into prosthetic devices. This should make producing practical body-powered and robotic limbs much more affordable in many countries, transforming the lives of thousands of people.

The team, which includes plastic and hand surgeons, has developed a prototype and hope to make the technology widely available for all to use.
