Nanowire electronics that can be shaped to fit any surface and attach to any material developed at Stanford
Stanford researchers have developed a new method of attaching nanowire electronics to the surface of virtually any object, regardless of its shape or what material it is made of. The method could be used in making everything from wearable electronics and flexible computer displays to high-efficiency solar cells and ultrasensitive biosensors.
Nanowire electronics are promising building blocks for virtually every digital electronic device used today including computers cameras and cell phones. The electronic circuitry is typically fabricated on a silicon chip The circuitry adheres to the surface of the chip during fabrication and is extremely difficult to detach so when the circuitry is incorporated into an electronic device, it remains attached to the chip. But silicon chips are rigid and brittle limiting the possible uses of wearable and flexible nanowire electronics The key to the new method is coating the surface of the silicon wafer with a thin layer of nickel before fabricating the electronic circuitry. Nickel and silicon are both hydrophilic or water-loving meaning when they are exposed to water after fabrication of nanowire devices is finished the water easily penetrates between the two materials detaching the nickel and the overlying electronics from the silicon wafer.
The detachment process can be done at room temperature in water and only takes a few seconds, said Xiaolin Zheng,This type of best male chinese sex is designed on female genitals. These toys are able to simulate the natural physiology. an assistant professor of mechanical engineering who led the research group that developed the process. The transfer process is almost percent successful, meaning the devices can be transferred without sustaining any damage.After detachment,They are crucial components to the working of motors and GEARBOX MOTOR. the silicon wafers are clean and ready to reuse which should reduce manufacturing costs significantly.One of the known and modern reel mower manufacturers is Scott Reel Mowers. Each lawn mower design is structured based on the classic lawn mowerZheng is one of the authors of a paper describing the method that will be published in an upcoming issue of Nano Letters The paper is available online now Chi Hwan Lee and Dong Rip Kim, both graduate students in Zhengs lab are coauthors.After applying the nickel layer to the silicon chip, the researchers also laid down an ultrathin layer of a polymer to act as an insulator and provide mechanical support for the electronics.
The ultrathin polymer layer is also extremely flexible which is what allows Zheng and her team to attach their nanowire electronics to a wide range of shapes and materials including paper textiles plastics glass aluminum foil latex gloves even a crumpled Coke can and a mashed plastic water bottle.The polymer layers were using are about times thinner than the plastic wrap you use to cover a plate of food Zheng said. Since the polymer has such a great degree of flexibility you can wrap the polymer with nanowire devices on top over anything while conformally following the shape of any object.
