The second generation primordial spirit hand had a tactile feedback function.
The biggest difference between machinery and flesh was that the former had no feeling.
If a mechanical hand was used to smash a wall, even if the mechanical hand was damaged, it would not feel anything. If it was a flesh body, it would be in so much pain that it would not want to live.
But often, when the tactile feeling was not so strong, it would bring people an extremely comfortable enjoyment.
For example, when holding hands with the opposite sex, the warmth from the hand would make people's hearts beat faster.
For example, touching an object, feeling the texture of the object's surface sliding through the hand, whether it was silky smooth, cold, or soft.
Tactile feeling could help people identify a lot of things, and it was also the most important way for people to feel other than their visual senses.
Of course, the mechanical hand had no tactile feeling.
Even if the machine was made to look real, it was still a dead object and could not help the user feel life.
When Dian Jing was recording a large number of bioelectric signals, she suddenly had an idea. What would happen if these signals were transmitted to the user in reverse?
The sensor chip collected the bioelectric signals of the human body, digitally converted them, and then transmitted the signals to the primordial spirit hand, allowing the primordial spirit hand to work according to the user's thoughts.
In theory, it was technically feasible to reverse this process and let the primordial spirit hand generate bioelectric signals and transmit them to the human body.
In the 2000s, electronic acupuncture and massage machines were popular for a while in television shopping, and they had similar functions.
However, this kind of equipment, which cost less than 100 yuan, could only emit a single bioelectric current, causing the muscles to beat uncontrollably under the stimulation of the electric current and feel a tingling sensation. To simulate the tactile feeling, there was still a technological gap between the earth and the moon.

Jiang Shuya took out a black object the size of a cigarette box. The back of this object had a layer of gel coating that could be attached to the skin.
"This is a tactile collector." Jiang Shuya introduced, "Monster Industries found that no one's nerve signal is the same after a large number of data analysis. These nerve signals can be used to distinguish users like fingerprints. "
"Men and women are different, and 20 years old and 30 years old are also different."
"Even different moods can affect the frequency of the nerve signal."
"So?" Wang Yanyu took the collector with his right hand and observed it curiously. He found that through the gel layer on the collector, he could see a complicated golden circuit diagram similar to an integrated circuit inside.
"Therefore, at present, the Essence Soul Hand can't perfectly reflect touch. It can't reflect deeper feelings such as itchy, wet, cold, smooth, and so on."
"Currently, it can only feedback the sensation of heavy objects, heat, pressure, and pain."
"That's enough." These feelings had far surpassed Wang Yanyu's surprise.
According to the instructions, it was best to place the tactile sensor on the other hand. The signals collected in this way could simulate the user's hand touch as much as possible. If you don't have hands, you can place them on your feet or face.
Wang Yanyu chose to stick it on the back of her right hand, and then activated the collector, using her right hand to collect the tactile sensation.
Starting from 100 grams, Wang Yanyu grabbed with her right hand in turn, 300 grams, 500 grams, 1 kilogram, 2 kilograms, and up to 10 kilograms. There weren't that many weights in the laboratory. Jiang Shuya simply took out a dozen bottles of drinks from the fridge to make up the numbers.
He shook hands with Jiang Shuya.
He tapped on the keyboard with his right hand.
She held the cup of hot water.
He gently tapped each finger with the probe …
The data collection work lasted for two hours. With the help of Jiang Shuya, Wang Yanyu collected almost all the tactile sensations she could come into contact with in life.
These tactile data would be stored in the chip of the Essence Soul Hand. Under the cooperation of the Essence Soul Hand's multi-dimensional force sensor, distance sensor, temperature sensor, pressure sensor, and so on, as many as 17 kinds of highly sensitive sensors. The Essence Soul Hand could accurately determine the situation of the object it came into contact with, and choose the most suitable tactile sensation from the database, and directly feedback it to the nerves at the end of the user's stump.
When the control wristwatch sent the notification that the data analysis was completed, Wang Yanyu's preliminary preparation work was also completed.
He stood up, took a deep breath, and put his right hand in his pocket.
Usually, when Wang Yanyu went out, he would put his left hand in his pocket.
Compared to an empty left hand, putting the "left hand" in the pocket would, of course, greatly reduce the curiosity rate of the surrounding people. So now, when Wang Yanyu was choosing clothes, he only chose clothes with loose pockets.
"The first test subject of the Essence Soul Hand is a teenage boy in our hospital. He can now use the Essence Soul Hand, and can do most of the normal hand functions other than playing Mobile Legends. "Jiang Shuya saw Wang Yanyu's nervousness.
"Oh right, that boy named Su Yuhang can even use the Essence Soul Hand to control the mouse. When I saw him playing League of Legends, he wasn't affected at all. "
"I won't let you down." Wang Yanyu turned around, and smiled with certainty.
…
Wang Yanyu had a staff meal at Mead Hospital before leaving.
He was now considered a non-staff member of Mead Hospital, and received an allowance of 500 yuan a day. After a while, when he went abroad, the allowance would rise to 2,000 yuan a day.
This wasn't the key issue, the key issue was that Wang Yanyu had become "left-handed".
Wang Yanyu usually took the subway when he went out. After coming out of Mead Hospital, he put his right hand in his trouser pocket, and walked coolly on the street with his left hand swinging.
It was summer, and his behavior easily earned him a look of "aren't you afraid of the heat?".
Wang Yanyu didn't care, and he would even touch his face with his left hand from time to time.
On his left hand, there was a touch that wasn't delicate.
On his face, he could clearly feel the same warmth as on his right hand.
It was such a beautiful first day, Wang Yanyu felt like he had been reborn a second time. From now on, his soul would be cleansed, and he would become even stronger.
His left hand took out the subway card from his pocket, and slid it across the card reader.
Following the crowd into the train, Wang Yanyu grabbed the handrail with his left hand.
Wang Yanyu only wore a long-sleeved shirt, but today he deliberately rolled up his left wrist.
The young men and women around him looked at Wang Yanyu with a strange look. Because ever since this guy entered the train, he had been staring at his left hand and giggling, with his right hand in his pocket the whole time.
A fashionably dressed young man seemed to have noticed his blind spot.
"Hey bro, where did you buy this wristwatch?" The young man waved the black Songto electronic wristwatch on his left hand.
Originally, his wristwatch was the most trendy model of the year, and many celebrities had worn it. But now, compared to the one on Wang Yanyu's wrist, it was as old-fashioned as it could get.
That wristwatch was a black polygon, with its appearance, material, and technological feel, it was obviously worth a lot.
If he also had a wristwatch, he would probably be like this uncle, staring at his wrist and giggling from time to time.
"Haha ~" Wang Yanyu laughed even more heartily, he extended his left hand and smiled: "Hello, my name is Wang Yanyu."
"Hi … Hello." The young man stiffly extended his hand and shook it twice, and then quickly pulled it away, not even in the mood to ask about the brand of the wristwatch.
The train stopped at a stop, and there was an empty seat next to Wang Yanyu.
He sat down and took out his phone from his pocket with his left hand.
Fingerprint identification passed.
Opened Mobile Legends.
Until Wang Yanyu used a smurf account to enter the battle mode, he was finally willing to take out his right hand.
His right hand was intact.
The young men and women next to him immediately hissed, this uncle was really pretentious.
