Imagine embedding a light, paper-based generator in the sole of a shoe, and charging your mobile phone when you walk, which would be great. According to a report by the American Physicists Organization Network on May 14 (Beijing time), scientists from the US Department of Energy's Lawrence Berkeley National Laboratory used a virus that is not harmful to humans to develop a technology that converts mechanical energy into electrical energy. The research results were published on the online version of "Nature-Nanotechnology" on May 13. The new power generation technology uses the piezoelectric properties of biological materials to generate electricity. The researchers applied a specially designed virus on the electrode, and tapped the electrode the size of a postage stamp with a finger. The virus then converted the force of the stroke into an electric current. Because the virus itself can enter an ordered film to drive the generator to work, this new type of generator points out a simple idea for manufacturing microelectronic devices. The researchers said that the new technology is the first time that it has taken a promising step towards personal generators, the use of drivers in nanodevices, and electronic equipment based on filtered germs. In the laboratory, the researchers used the human-friendly virus M13 phage that only attacks bacteria and can replicate millions in a few hours, so it is stable in supply. These baculoviruses can naturally orient themselves in the film and align like chopsticks in a box, which is what scientists are looking for in nanostructures. In the study, the researchers increased the piezoelectric strength of the virus, using genetic engineering to add 4 negatively charged amino acid residues to the helix protein and cover the virus. These residues can increase the charge difference between the two ends of the protein, thereby increasing the voltage of the virus. The study also found that a stack with a thickness of about 20 has the strongest piezoelectric effect. They also assembled a prototype virus-based piezoelectric energy generator. They managed to let the genetically engineered virus spontaneously organize into a multi-layer membrane of about one square centimeter, and then sandwich the membrane between two gold-plated electrodes and connect it to the LCD through wires. When pressure is applied to the virus, the generator can produce up to 6 nanoamperes of current and 400 millivolts of voltage, enough current to flash the number "1" on the screen, which is equivalent to about 1/4 of the voltage of a 3A battery. The researchers say they will improve the principles in the prototype. Since biotechnology tools can produce genetically modified viruses on a large scale, in the future, virus-based piezoelectric materials can provide a simple path for new microelectronics technologies.
