Many times, disasters will suddenly come and change a person's life. Earthquakes, fires, car accidents or diseases, after the disaster, the surviving people may have to face their own incomplete physical body, and the long-term mental torture and psychological damage that the physical disabilities will bring, it is difficult to heal.
Thanks to the efforts of many ideal scientists, people can make up for the physical defects through various precise prostheses. These prosthetic limbs can be very realistic and futuristic. Hands can do simple movements, legs can walk normally, run, almost perfect to see no flaws, but they have a regrettable flaw, that is, no feeling.

Only let these cold and numb prosthetic limbs have a sense of touch, so that the skin transplanted after burn can have a feeling, those who are hurt can feel the touch, caress, feel the temperature, feel the love they love through their prosthetic limbs. In this world, perhaps their inner pain can be really compensated.
The feeling of touch comes from the skin, how to make the artificial skin touchable. One scientist has been doing all kinds of efforts and attempts. She is a professor of chemical engineering at Stanford University and a Chinese female scientist Bao Zhenan.

Professor Bao Zhenan hopes that this artificial electronic skin can reach a more ideal state. It can not only sense the external pressure, but also feel the light weight of the object. It is durable, flexible and has the same skin-like ductility. It can be like real skin. Self-repairing after cutting, it is also possible to process and transmit sensory signal data, and finally to effectively combine with the human nervous system to transmit the sensation to the nervous system.
Our medicinal synthetic polyisoprene gasket for injection does not contain any substances that can easily produce pyrogen. We now use a unique technique to add cytotoxicity to the routine test of butyl rubber stoppers such as pyrogen, hemolysis, acute systemic toxicity test and so on. Systemic injection test and intradermal stimulation test have been used abroad for many years.Our good puncture resistance ensures the minimum rate of chip drop during the puncture process and our good self-sealing performance can guarantee no leakage during using process in hospital.Also,good retention of puncture device ensures that there is no needle slider and needle drop in the process of hospital use.
