"The size of this chip is about 20×20×7 cubic millimeters, and it can be implanted in the arms, back, abdomen, etc. People can turn on the contraceptive mode through remote control, and the chip will release the micro contraceptive hormone implanted under the skin into the blood. Compared with drug contraception, this kind of wireless implantable remote control chip is very convenient, and the duration can be as long as 16 years. You see, the current technology has such a cutting-edge discussion, let alone 500 years later, you I have to give me some time to study slowly. Maybe you really have a pacemaker in your body, which is so small that it can be ignored. Give me some time to check it slowly. I can’t eat hot tofu if I am impatient."

Lonely Shan spit on him abruptly: "No wonder your wife dislikes you for talking."

Ji Yiming's eyes are convex: "How do you know?"

"You can tell by looking at the face." Lonely Shan doesn't want to listen to him long-winded: "It's okay to tell you that if someone holds a remote control, my heart that no longer beats will beat, and it will be accompanied by unbearable pain. Check it quickly and don't talk about it."

"Remote control?" Ji Yiming thought for a moment: "Will it be a non-implantable pacemaker? I told you that you are definitely looking for the right person when you came to see me today. You should always come to find out about it. With cutting-edge technology, scientists have now proposed that there is no need to implant any devices, only laser irradiation can control the rhythm of the heartbeat, and experiments on fruit flies have made it a reality."

Lonely Shan listened with great interest, and asked him, "How does the non-implantable heart beat?"

Ji Yiming can't wait to show all his knowledge, so as to win a different look at Lonely Good, so as to gain the trust of Lonely Good, so that he can study Lonely Good in the future.

He said: “All cardiac pacemakers are based on the fact that every heartbeat is caused by electrical pulses that pass through myocardial cells. The contraction of the heart allows blood to circulate in the body. Electrodes for implantable pacemakers Provide a stable pulse to the heart tissue to keep the problematic heart beating regularly. But in an experiment, scientists irradiated an anesthetized fruit fly with a blue laser to keep its heart rate in line with the rhythm of the laser pulse Consistent, beating at a rate of 10 times per second. Researchers claim that this light-based non-invasive technology may be able to achieve a new generation of cardiac pacemakers in the future. Related papers were published in the digital open access journal Science Advances On, if you are interested, you can look up related papers."

"This study used Drosophila melanogaster as the research object, because in the early stages of heart development, they have many similarities with vertebrates. The researchers first extracted a light-sensitive protein gene from algae and bred it to contain this protein. The fruit flies then use laser light from the outside to activate heart cells containing light-sensitive protein. This light-sensitive protein is named channelrhodopsin-2, and once it comes into contact with the blue laser, it will cause the heart to contract."

"The professor in charge of this research pointed out that compared with traditional cardiac pacemakers, optical stimulation has incomparable advantages: this non-invasive technology only triggers target cells, while electric pacemakers must be surgically implanted. , The electrical impulse will not only affect the heart cells, but also other tissues."
