Modern anthropomorphic prosthetic and robotic hands are not capable of meeting desired values in all the five criteria of size, weight, strength, speed and dexterity. A key reason for this is that existing actuators combined with transmissions with constant reduction ratio are unable to achieve performance that addresses all of the above criteria. Continuously Variable Transmissions (CVTs), which ...Show More
Extrinsically powered prosthetic wrists have the potential to offer significant improvements to the functionality and dexterity of a prosthetic hand. They can also reduce a user’s overreliance on their intact limb and help prevent injury from overuse of upper limb (both intact and residual) and trunk joints. Despite these potential advantages, there are very few prosthetic wrist options that are c...Show More
Extrinsically powered prosthetic hands offer the potential to replicate the capabilities of a human hand and thus enable an upper limb amputee to complete activities of daily living. Over the past 20 years however, amputees have consistently indicated that several user needs have not been met. Many of these user needs are related to the hardware of the prosthetic hand, and in particular, its actua...Show More
