Scientists are researching sound wave battery charger

The people who like to have a long cell phone conversation maybe become the energy maker in the future

. Korean scientist research sound wave battery charger, it is hopeful to change the sound wave into electricity. Like this, the longer the call, the fuller the cell phone battery. The research report was published by . A vision Korean scientist abstract a kind of minor material which can change the sound wave into electricity energy from calamine solution, a kind of energy panel can be made by this. This energy panel charge cell phones by changing the sound wave generating when talking into electricity energy or supply to national grid by changing the noise of traffic peak into electricity energy. ABC reported by quoting the word of the researcher leader Piao Yongjun and Jin Xiangyu, the loudspeaker can change the electrical signal into sound, on the contrary, it is possible to change sound into electricity. "Sound can have varieties of curious application, for example, the cell phone charged by talking sound, the sound-proof wall generated electricity power utilizing the voice of traffic in the side of highway." Research report reveals. The material can be abstracted energy from calling voice and traffic is called "piezoelectric". When this material is bending, the mechanical energy can be changed into electricity energy. Piezoelectric Many materials are piezoelectric, such as sugar, quartz, even dry bone. In several decades, scientist put electricity into the piezoelectric materials, using them in environmental sensor, loudspeaker and other equipment. In last several years, the scientist tried to abstract electricity energy from piezoelectric device and achieves important improvement. Most piezoelectric device can generate electricity energy at the same time of walking, running and talking by a person, but consumer can not buy this device now. American army even imagines changing the physical impact of the bullet into weak electrical flow to supply part of energy for vehicle. The Korean scientist hopes utilize a kind of different energy ? sound wave. The researcher uses zinc oxide which is the main ingredient of calamine solution to make some nanometer wire sandwiched between two electrodes, then impact this set of electrodes assembly by 100 decibel sound wave, it generates about 50mV electricity flow. To be mature The volume of experimental sound wave is less than the volume of a rock concert, while the volume of people's conversation is about 60-70 decibel. Normally, a cell phone working need several volts electrical energy (cheap cellular phones), is several time as the electrical energy generated by this experiment. American Princeton University scientist Michael Mcalpine is also researching the equipment can gain energy. He says, the research of Korean scientist is interesting, "but the real question is if there is enough environmental noise can supply cell phone energy". The consumer maybe does not want to attend a rock concert, or charging cell phone standby the running train (wholesale cell phone accessories). The Korean scientists agree this point. They said, 50mA is not a very strong electricity flow, but this research has verified the conception of sound supplying electrical energy. The researcher will develop the equipment can output more electrical energy. From: cheap cell phone
