New Discovery of Graphene Composites: Prospects for Wireless Generators
In 1897, Nikola Tesla’s “Most Amazing Way to Universally Transmit Strength†made headlines and sparked the initial construction of the famous Tesla Tower in Long Island, New York (ie, A giant giant with a diameter of 68 feet and a height of 187 feet. One hundred and twenty years later, the research team of the Clemson Nanomaterials Institute has now developed a wireless power transmission device based on new graphene and polylactic acid-based 3D printed nanocomposites. Tesla model. The device is the first renewable energy generator that can be wirelessly transmitted. The biggest feature is that a 2400V electric field is generated by a finger click, and a binary code of more than 3 meters can be transmitted.
Energy symmetry
According to the sustainable development of renewable energy, the Clemson researchers are keen to identify a rich, biodegradable and recyclable material on Earth. The friction or piezoelectric properties of a material are determined by the crystallographic symmetry of the material, and the material properties disappear when the lattice has a symmetric center. However, based on previous research by Japanese researchers, the Clemson team showed that they can eliminate the symmetry center of biopolymers by adding polarized molecules to asymmetric carbon atoms in their chemical structures.
The ideal materials researchers expect are source plants and biodegradable, and contain two asymmetric carbon atoms. Polylactic acid has such characteristics. However, the resistance of PLA for TENG devices is too high, so researchers use graphene as a filler to produce nanocomposites for combination with highly negative polymer Teflon in 3D printed wireless TENG.
Researchers
Podila and his colleagues explained: “We are not surprised at the high voltage generation, but we are excited about the discovery of wireless signals that can be sent and received without interference from the surrounding environment, such as WiFi, cell phones, and power supplies. Sockets, etc. "They apply their devices to the energy collection and transmission capabilities of a range of home appliances, namely smart color windows, picture frames, LED displays and a call bell/security alert.
The prospect of wireless generators
3D printing allows inexpensive scalable manufacturing with different patterns for the purpose of improving efficiency, and wireless generator devices with multiple wireless generator layers connected in series. It also creates opportunities for future integration of device manufacturing with the automotive, textile and electronics industries.
An exciting application for this device is an intelligent path that can take advantage of people walking to provide mechanical energy. Energy cleanup corridors may sound like science fiction, but researchers have patented the technology and envisaged working closely with industrial partners to bring it to market within the next two or three years.
Researchers are currently developing a two-dimensional sheet material that “beyond graphene†to expand other potential uses of W-TENG, including low-power lasers, photodetectors, and biosensors that do not have power outlet requirements. Researchers described this "cut off rope" method as "the need to improve healthcare in low- and middle-income countries without reliable electricity."
Researchers are now developing more environmentally friendly two-dimensional sheet materials that go beyond graphene to replace Teflon with high conductivity. Future work directions also include specific user's "fingerprint" sensitive W-TENG developed for home security applications. Among them, collaborators SaiSunilKumarMallineni and HerbertBehlow focused on the development of W-TENG biosensors, while Dong Yongchang and ApparaoRao and RamakrishnaPodila are developing new materials to replace Teflon.
The mechanical Buzzer uses a magnet to move a reed up and down quickly to emit a lower-pitch buzz! It's quieter than the piezoelectric buzzer but uses more power, so you the terminals will have to be closer to the battery packs. To use them, you'll need to match the wire colors to the wires from the battery pack.
