Growing human tendons on an advanced robotic hand

This apparently is NOT NEW news, but I only came across this a few days ago!

Researchers first created a robot hand that is so accurate it has almost the same dexterity as a human hand. This is a major leap for prosthetics, and the motion capabilities of this hand have never been seen before.

Researchers put the hand through a laser scanner and then 3D printed artificial bones to match, they plan to then grow human tendons and tissue on the robot hand!

Currently, in the event of amputation of the hand patients currently have one of 3 options available to them:
Hand replantation: This is only a viable option if the severed hand is professionally cared for immediately after the accident and the tissue is healthy.
This procedure is carried out of if the hand can function without pain. The goal would be to give the patient back as much function as possible.
Amputation: Required if the tissues are too damaged and the hand cannot be replanted. A cosmetic or prosthetic hand may be offered to improve the cosmetic appearance and function of the hand.
Hand transplantation: If a hand replantation is not an option, surgeons can offer the patient a hand transplantation. This would involve a donor hand being transplanted. An operation like this requires a team of up to 20 surgeons who connect the arteries, veins, tendons and bones. Immunosuppressants are needed to prevent rejection of the donor hand by the patient’s body.

The new prosthetics hand would mean people could have an entirely new hand, human skin and all, if their hand were to be lost in an accident.
