Technology has been closely linked with the people, in fact, the body itself is a complex "machine" and continuing to acquire and release energy, this mechanism is even expected to affect the future development of battery technology.
As we all know, lithium battery technology has been developed almost to the end, no further meet human needs, but scientists are actively developing new types of batteries, may be graphene, solar, sound power, silicon, sodium, or other organic matter, yet there is a conclusive ʱ?? The researchers also found that, due to human releases 2000-2500 calories per day, enough to supply a number of electronic products, so "biofuels" has become a direction for the future development of the battery.
Organ Generation
Studies have shown that mammalian cochlea contains a tiny voltage, known as the "inner cochlear potentials" (Endocochlear Potential), the pressure can be converted to electrical pulses. Theoretically, it is entirely possible for micro-power devices such as hearing aids supply.
2012, Massachusetts researchers have successfully developed energy harvesting chip size of a fingernail, and Cochlear implants can generate 1 ng watts per minute. Although less power, but the high output power chip has been put into research and development, the future can be implanted in the patient's ear hearing impairment, hearing their power.
Piezoelectric and thermoelectric materials
Body like a machine, working almost constantly emit heat, such as muscle movement, heart rate, breathing and so on. In fact, in the past few years, researchers have found one of the most effective and simple method of human power, electricity is generated by human movement, called "piezoelectric generation." At the bottom of the shoe integrated piezoelectric material, you can continue to generate electricity through the human walking motion, energy in 2013 by a Sino-US research team issued a piezoelectric fiber collecting volunteers walking, can produce 30 LED lighting; and volunteers wear clothes made of piezoelectric fibers, then normal movement, it is possible within a few hours the Li-ion battery is fully charged.
In addition to piezoelectric technology, a thermoelectric power generation is a promising biomass power generation technology. This year, the Chinese and Australian researchers to develop a thermoelectric fabric that can absorb heat from the human skin, and converted into electricity.
Humoral Generation
One-third of the human body is composed of water, which means a variety of human body fluids full value. Although blood generation sounds a bit frightening, but it contains a lot of ability, but currently only been tested in mice, human blood generation seems difficult to achieve.
Of course, we also sweat, tears or urine can be used. First, sweat contains a wealth of lactic acid, can be used to generate electricity, in 2013 American researchers at the University of California has created a sweat power generation equipment, volunteers will wear it on your arm movement for 20 minutes, sweat is converted to electrical energy, can be charging for mobile phones and other mobile devices, it demonstrated the potential of this technology.
Secondly, tears contain glucose, lactic acid, ascorbic hydrochloric acid and other substances, it can also be an excellent fuel. University of Utah researchers have successfully created a smart contact lenses, it can be powered by tears.
Human urine is discharged, in fact, also has a great value. Bill Gates Foundation to support the Bristol Robotics Laboratory, created a set of urine as a raw material for biomass power generation system to produce electricity through microbial decomposition of the urine, compared to other types of waste more efficient. That is, the system is integrated in a public toilet, urine provided power grid can even relieve pressure on the city to some extent, great development space.
