Su Yuhang pressed the button.

The black screen of the electronic watch then lit up, and Su Yuhang also noticed a clear tightening sensation from the connection of the bionic hand.

The stump of the wrist is tightly connected with the bionic hand.

His mother quickly asked how she felt.

“I don’t know…” Su Yuhang was so nervous that his wrists were shaking.

The period of hospitalization has made him feel from being unacceptable at the beginning to being completely desperate now. Now Su Yuhang looked at his right arm, and there was an avant-garde electronic watch that just covered the bionic hand, and the imperceptible edge of the wrist.

Everything was like before that car accident, his right hand was intact.

However, the physical presence of the right hand has not been noticed now.

“Now that the bionic hand is activated, you can try to shake your hand.” There is an extra tablet in Ye Qing’s hand, which shows the current working parameters of the bionic hand and the information received by the sensor patch.

Su Yuhang stayed in the same place for more than ten seconds, only when faint beads of sweat appeared on his forehead, he suffocated a sentence, “I don’t know how to hold it…”

Jiang Shuya was also very nervous. After realizing that Su Yuhang had not received professional electromyography prosthetic operation training, she quickly said: “Yuhang, didn’t you tell me a few days ago that you obviously lost your right hand, but your right hand often hurts in your mind. Does it feel like you are coming?”

“This condition is called phantom limb pain, which is a passive functional reorganization of the nerves at the end of the hand and the cerebral cortex when the right hand is suddenly lost.”

“The pain will gradually disappear over time, but the longer the time, the more the nerve will forget the control function of the right hand.”

“Yuhang, close your eyes now, don’t look at your right hand. Recall how you opened and squeezed your right hand before, and redo it in your mind.”

Su Yuhang quickly closed his eyes.

But within a few seconds, he was awakened by his mother’s screams.

His right hand was released, as if he unconsciously loosened it in his sleep, and then quickly clenched it.

Of course Su Yuhang realized that even if he was not conscious, the visually completely real picture made his eyes burst into tears.

“That’s how it feels. Keep your eyes open and keep trying.” Jiang Shuya encouraged.

Young people are usually very smart, and Su Yuhang quickly mastered the skill of commanding bionic hands.

By imagining that the right hand is moving, the nerves and motor muscles at the end of the residual limb will naturally release motion signals. These signals are captured by the sensor patch, transcoded into digital signals, and drive the bionic hand to work.

Theoretically, the shorter the time to lose the right hand, the stronger the movement signal from the residual limb.

Because of this stage, the corresponding nerves and muscles have not degenerated.

The bionic hands were one and the other, Su Yuhang’s excitement broke out at this time, more intense than the moment when he first saw Ye Qing.

His parents were tearful in their eyes. In their eyes, even if the bionic hand can only be combined one by one, visually, there is no trace of any mechanical movement. There is no sound, and there is no sense of frame dropping.

They can guarantee that as long as they bring this bionic hand, Su Yuhang will not receive any curious eyes from passers-by.

Ye Qing watched the data uploaded from the tablet computer all the time. Seeing that Su Yuhang was already able to master Zhang He with his right hand, he was still satisfied and asked him to try to grab the object.

The Prosthetic Installation Center has a wide range of exercise items, from the most common water cups, switches that require knobs, to more complex buttons for clothes.

Su Yuhang staggered to the side and stretched out his bionic right hand to the cup placed on the coffee table.

There was tea in the cup that had been brewed soon, and the bionic right hand also firmly grasped the cup. The cup was put down, his confidence was greatly encouraged, and he reached out to a very common air-conditioning knob switch.

Unexpectedly, the limitation of the induction patch appeared.

He obviously wanted to stretch out his thumb, thumb and index finger to pinch the knob. It can be transformed into an actual action, which is indeed the action of grabbing a water cup. The bionic right hand opens and holds the knob.

Su Yuhang tried again, and then stood there blankly.

“This action can be done.” Jiang Shuya walked around behind him and said softly: “For Ottobock’s product, it can do more than 30 different finger linkage actions, corresponding to seven main gestures. Function.”

“For example, before twisting the knob, the user should lightly tap the little finger and ring finger with his left hand. These two fingers will not be involved in the subsequent exercise process.”

“The one you bring now may not have this feature added.”

Su Yuhang didn’t know what he was thinking, and was a little distracted.

Ye Qing looked at the data on the screen, frowning and thinking.

The bionic hand composed of thermal neurons is of course ten times more advanced than Ottobock’s mechanical movement. However, using the same sensor patch technology, no matter how advanced the bionic hand is, the patient can only make the same movements as the latter.

Of course this was not what Ye Qing wanted.

Inside this pair of bionic hands, a variety of micro-sensor technologies transplanted from the Watcher X robot are integrated.

Ottobock has always liked to boast its own three-dimensional force sensor, but in the hands of the bionic hands of the giant animal industry, the six-dimensional force sensor is only a very low-level configuration.

The problem is that these configurations cannot help users make the posture they want.

Ye Qing waved to Jiang Shuya, who asked why?

“I think the problem is in the sensor patch.”

Ye Qing pointed to the data just collected on the screen, “Yuhang just wanted to make a three-finger pinch knob movement. It is obvious that the bioelectric signals released by muscles and nerves are different from the signals when he wants to hold an object. Inductive stickers The film still treats it as the simplest open hand, and then hold the hand.”

“It’s complicated, it can’t handle it.” Jiang Shuya took a deep breath and whispered: “Grabbing objects is the most commonly used function of hands in life. There are some manipulators worth several thousand yuan in China, but this is the only one. Function.”

“Ottobock is mainly advanced in sensors and function expansion. It has more flexible finger movement, the wrist can be rotated, and the mechanical finger can be touched with the other hand to activate more complex movements.”

“Why can’t it be handled?” Ye Qing interrupted: “I have removed this sensor patch, and it uses metal electrodes to sense muscle motion signals. In theory, through signal amplification, it should be able to sense organisms on the order of microvolts. Voltage changes.”

“If you are afraid of signal interference from electronic devices in your life, you can completely isolate it with a shielded sports wristband or other things.”

Jiang Shuya looked at Ye Qing innocently, but she couldn’t understand.

“You have a technician from Ottobock here, let him come over.”

“Yes, but…” Jiang Shuya shook her head quickly.

The Prosthetic Experiment Center was originally invested and constructed by Ottobock Company, and one of the three persons in charge in it was an expatriate person from Ottobock Company.

But at this meeting, Jiang Shuya did not notify Ottobock.

She was mainly worried about the Ottobock company. She wanted to pull Ye Qing to talk about cooperation.

Cooperation can be discussed anytime, but at the first meeting, Jiang Shuya still hopes to devote her energy to product testing and discussion.
