Shanghai high-tech gadgets showcased at Shenzhen fair
A new microneedle therapy on show at the Shanghai section of the China Hi-Tech Fair provides painless injections and reduces the risk of infection.
The therapy is one of 50 high-tech projects that Shanghai companies and organizations took to fair in fields including green energy, information technology and intelligent manufacturing.
The microneedles ,developed by Shanghai Institute of Technology, are tightly clustered together on a platform which is similar in size to the absorbent pad of Band-Aid. Made of poly-L-lactic acid, polystyrene or hyaluronic acid come loaded with the drug to be delivered. They are extremely fine and even if some break under the skin, they will dissolve harmlessly.
Developer Zhang Yu told Shanghai Daily that the microneedles leave no obvious scar.
"Even you use a very thin metal needle, you still feel pain," said Zhang. "Microneedles cause only very slight itch for new users."
Shanghai University has taken an E-repair bio-printer. Graphic printing can help with emergency treatment such as stopping a wound from bleeding and can create artificial blood vessels. The device uses a unique biological ink and provide comprehensive solutions for emergency rescue.
"With this device, people can give first aid to themselves at the scene," said He Xiaolong, a research student at the university .
The Jinghai unmanned surface vehicle (USV) plays multiple roles in oceanic exploration and rescue.
The university also took the Jinghai unmanned surface vehicle (USV), effectively a water-drone. These vessels can enter the areas that people are unable or unwilling to go. Last year they were used in cleaning up the marine oil slick caused by the sinking of oil tanker Sanchi.
