Su Yuhang pressed the button.

The black screen of the electronic watch illuminates, and Su Yuhang also notices a clear tightening feeling from the junction of the bionic hand.

The residual limb of the wrist is tighter to the bionic hand.

His mother quickly asked how it felt.

"I don't know..." Su Yuhang was nervous and his wrists were shaking.

The period of hospitalization has already made him feel, from the initial unacceptable to the now complete despair. Now Su Yuhang looks at his right arm, where he has an avant-garde electronic watch that just covers the bionic hand and the connection edge that is not easily noticeable at the wrist.

Everything was like the car accident, his right hand was intact.

However, it is now impossible to detect the presence of the right hand.

"Now the bionic hand has been activated, you can try to hold your hand." Ye Qing has a tablet in his hand, which shows the current working parameters of the bionic hand and the information received by the sensor patch.

Su Yuhang spent more than ten seconds in the same place. When the forehead was faintly sweaty, he said, "I don't know how to hold it..."

Jiang Shuya is also highly nervous. After realizing that Su Yuhang has not conducted professional training on myoelectric prosthetic operation, he quickly said: "Aerospace, you didn't tell me a few days ago, obviously lost your right hand, but your mind often has a pain in your right hand. Does it feel like it?"

"This condition is called phantom limb pain, a functional recombination that is carried out passively by the terminal nerves of the hand and the cerebral cortex in the event of a sudden loss of the right hand."

“The pain will fade away over time, but the longer it takes, the more the nerves forget the right hand control.”

"Aerospace, you close your eyes now, don't look at your right hand. Recall how you used to open and hold your right hand and redo it in your mind."

Su Yuhang quickly closed his eyes.

It took a few seconds and was awakened by the screams of his mother.

His right hand was done, just like unconsciously letting go of his sleep, and then quickly clenched.

Su Yuhang certainly realized that even without consciousness, the visually complete picture made him tearful.

"It is this feeling, you squint and continue to try." Jiang Shuya encouraged.

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

By imagining the right hand, the nerves and moving muscles at the end of the stump will naturally release a motion signal. These signals are captured by the inductive patch and transcoded into digital signals to drive the bionic hands.

In theory, the shorter the distance from the right hand, the stronger the motion signal released by the residual limb.

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

The bionic hands are in one, and the excitement that Su Yuhang broke out at this time is stronger than the moment when he saw Ye Qing.

His parents have tears in their eyes. In their eyes, even if the bionic hands can only be a single one, they can visually find no trace of mechanical movement. There is no sound, and there is no sense of lost frame.

They can guarantee that with this bionic hand, Su Yuhang will not be subject to any curious eyes of passers-by.

Ye Qing is looking at the data uploaded by the tablet computer. Seeing that Su Yuhang has mastered the right hand Zhang He, he is still satisfied, let him try to grab the object.

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

Su Yuhang walked aside and gave a bionic right hand to the cup placed on the coffee table.

There was a cup of tea in the cup, and the bionic hand grasped the cup steadily. The cup was lowered and his confidence was greatly encouraged, reaching out to a very common air conditioning **** switch.

Unexpectedly, the limitations of the sensor patch appeared.

He clearly wants to stretch his thumb, thumb and index finger to pinch the knob. It can be converted into actual action, it is indeed the action of grabbing the cup, and the bionic hand holds the **** with the right hand open.

Su Yuhang tried it again and then stood still.

"This action can be done." Jiang Shuya went around him and said softly: "With Otto Bock's products, it can do more than 30 different finger linkages, corresponding to seven main gestures. Features."

“For example, before turning the knob, the user should first tap the little finger and the ring finger with his left hand. These **** will not participate in the subsequent movement.”

"The one you brought with you may not have added this feature."

Su Yuhang did not know what he was thinking, and he was distracted.

Ye Qing looked at the data on the screen and frowned.

The bionic hand made up of thermal neurons is of course ten times more advanced than the mechanical movement of Otto Bock. However, the same sensor patch technology is adopted. No matter how advanced the bionic hand is, the patient can only perform the same action as the latter.

This is of course not what Ye Qing wants.

Inside the pair of bionic hands, it integrates various miniature sensor technologies transplanted from the Watcher x-type robot.

Otto Bock has always liked to blow its own three-dimensional force sensor. In the double bionic hands of the behemoth industry, the six-dimensional force sensor is also a very low-level configuration.

The problem is that these configurations don't help the user make the pose they want.

Ye Qingchao Jiang Shuya waved his hand, what did the latter ask?

"I think the problem is on the sensor patch."

Ye Qing pointed to the data that was just collected on the screen. "Just like Aerospace wants to make a three-finger knob, the bioelectric signal released by the muscles and nerves is different from the signal when he wants to hold the object. The film still handles it as the simplest open hand and then holds the hand."

"Complex, it can't handle it." Jiang Shuya took a deep breath and whispered: "Grabbing objects is the most used function in your life. There are only a few robots worth thousands of dollars in China. Features."

"Otto Bock, mainly advanced in sensors, and functional expansion. Its finger movement is more flexible, the wrist can be rotated, and the mechanical finger can be touched by the other hand to activate more complex movements."

“Why can't I handle it?” Ye Qing interrupted. “I removed this sensor patch, which uses metal electrodes to sense muscle motion signals. Theoretically, by signal amplification, it should be able to sense 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 something else.”

Jiang Shuya looked at Ye Qing very innocently, she could not understand.

"You have Otto Bock technicians here, let him come."

"Yes, but..." Jiang Shuya shook her head.

The Prosthetic Experiment Center was originally invested and built by Otto Bock. One of the three responsible persons, there is an expatriate from Otto Bock.

But this time, Jiang Shuya did not inform the Otto Bock company.

She was mainly worried about the Otto Bock company. When she came up, she wanted to pull Ye Qing to talk about cooperation, and then the entire hospital leader was stunned.

When can I talk about cooperation, but for the first time, Jiang Shuya still hopes to use her energy in product testing discussions.
