Stanford University's female professor Bao Zhe Nan, who invented artificial electronic skin last year, is targeting the search for “super skin†that is more sensitive than human skin. Her research team recently creatively developed the world's latest stretchable solar cells, adding new capabilities for self-generation to artificial electronic skin, and at the same time elevating human research on electronic skin to a new stage.
Bao Zhenan said in an interview with a reporter from the China News Service on the 23rd, “We have demonstrated that solar cells can be stretched like artificial skin. Such artificial skin can not only mimic the sensitivity of human skin, but also exceed and add human skin. There is no power generation function."
The world's first new type of solar cells are made of special plastics. They have very flexible and flexible characteristics. They can be stretched to 30% of their own length and the function will not change. There is no damage after recovery and no power loss. The artificial electronic skin produced by this can generate electricity by itself and can operate without a power supply. At the same time, this special plastic is made of biodegradable materials and is environmentally friendly.
Bao Zheonnan said that the difference between her achievements and other scholars is that “the existing research is to connect one solar cell to another with a single wire and make a net. This net can be stretched, but we have a single solar energy. The battery can be stretched."
This new feature will expand the scope of use of artificial electronic skin, Baozhan Nan said, "Foldable field camping tents, you can use this flexible solar cell, do not worry about battery damage." Other uses include clothing, robots and prosthetics Wait.
Bao Zhennan from Nanjing, China, is an associate professor of chemical engineering at Stanford University. Last September, her research team invented a high-sensitivity film material that felt the intensity of a butterfly or flies gently falling. Artificial electronic skin made of this material has brought new breakthroughs in medicine and human life.
"Imagine a robot hand made of artificial electronic skin that can detect biomolecules and determine what kind of illness he has," says Bao Zheinan. "After the robotic hand touches people's sweat, he can judge whether he has drunk. ."
Manufactured from themoplastic EPDM and Brass, these clever toggle fasteners have numerous applications. Most often used to secure hardware and other objects to thin steel, aluminium, plywood or fibreglass surfaces where there is no access to the cavity.
With a captive Brass Nut, the toggle expands within the cavity as it is tightened. The rubber-like compound provides a seal against water and salt penetration while insulating against vibration.
Available in a range of sizes to suit many applications onboard your vessel.
Sold individually, with automatic discounts for purchases over 1000 units.
Note that the nuts have metric threads and the bolt is not supplied.
M3,M4,M5,M6,M8,M10 & M12 also available
