bionic arm

In the era of digital life, making human life easier and smarter. Life is full of challenges. Challenge of getting good wealth, more success, etc., but what if living a normal life becomes a challenge? When you lose the utilization of a limb, even the simplest of everyday activity can become a challenge. Today, our aims have been levelled to get back some of the lost function, this needs some kind of adaptive technology to either get better recovery or re-establish the ability of the mortal part that’s missing now. In fact, it is one of the biggest challenges in itself for healthcare, where engineers have to cope up with nature.

Designing a few devices that must achieve the same function as a natural part of the body or coordinate with natural phenomena. This rapidly-changing research intends to enhance people’s lives by recovering both movement and feeling. Replacing missing or lost limbs provides some of the best eye-catching examples of the achievements we have made. The bionic study had come up with the idea of bonding the human nervous system to computers. Bionic prosthetic devices are the name for these artificial limbs.

How is a Prosthetic Device or bionic arm made?

“If they were wearing a cosmetic hand or a hook at a young age, like at school, it would make them want to hide their limb.”- Samantha Payne, Open Bionics. In general, carbon fibre makes a prosthetic arm or leg strong and durable. We don’t notice how much our limbs weigh because they feel so natural and appear to move. So, the material is Lightweight. Foam padding or flesh-coloured plastic coating enables this. Considering the total weight of the body, assume that two legs amount to 30–40% and two arms about 10%.

Now, this is why it is necessary that prosthetic limbs have to be much lighter. Through the use of prosthetic limbs that weighed as much as natural ones; it is possible to prevent tiredness quickly. Including a user’s natural strength, the bionic limb can lift approximately 40 pounds of weight. “Any a part of the body—from your ear or nose to your finger or toe—could be replaced by a prosthesis.”

How can somebody who has lost a limb control a prosthetic?

“When someone loses a hand, their brain is networked as if the hand is still there,”Huang says. Bionic arms work by taking signals from a user’s muscles. By connecting an external device to the human nervous system researchers have traditionally used a setup that records brain signals from the user. It computationally analyzes those signals to figure out the user’s intentions. And, then transmit the information to an external effector that works on those intentions.

By tensing the same muscles, control of the bionic arm is possible. To close the hand, and perform the selected grip, imagine flexing the wrist inwards while pulling the fingers into the heel of the hand. To open and, imagine extending the wrist with an outstretched palm. The phenomenon of myoelectricity helps achieve control. The person does not require surgery; we simply identify a user’s strongest muscle sites and take a 3D scan or cast of their residual limb before custom building a Bionic Arm.

Prashant Gade had built this bionic arm at a very cost-effective price to make it affordable. About his Inali foundation – “Brainchild of Prashant Gade, Inali foundation, a non-profit section 8 organization was started in 2016 with the aim of providing affordable upper limbs to those who have lost them in an accident or don’t have them by birth. Inali foundation, in 3 years has provided over 1500 upper limbs to people from all across India. The two variants of upper limbs that the Inali foundation has distributed are simple silicon made cosmetic gloves and Mayo arm. Inali foundation is proud to say that the entire limb is manufactured and assembled in India.”
