Scientists Want to Recharge Batteries With Body Energy

///Scientists Want to Recharge Batteries With Body Energy

Batteries are a weakness of the mobile industry. Increasingly powerful, mobile devices require smart solutions to take better advantage of battery power and also recharge faster the power repository of a tablet or smartphone.

Thus, many researchers have sought alternatives to the traditional ways of powering a device. One of the bets is the use of mechanisms capable of collecting energy from the human body, thus dispensing with the use of conventional batteries.

This innovation would be of even greater use in the healthcare industry. If you imagine a device that needs battery power to continue working – like a brain or heart implant – having to remove it to “change the battery” may be something laborious and risky.

“If a device relies on batteries, replacing them would require surgery, then providing medical device resources is a significant advantage and can really affect people’s lives,” argues the professor at the University of Southern California in the United States, Dina El-Damak.

From the heat

The most obvious method when talking about this is to get energy from the movement, but many scientists do not bet on this mode for a reason also quite evident: not all devices can afford to function only when the carrier is in motion.

One option considered by some researchers is the piezoelectric method, which generates energy from the pressure applied to certain materials.

However, the favorite of scientists is the energy generated from the heat of the human body, something that we never fail to produce while alive. This method is called thermoelectric generation.

An example of this comes from the University of North Carolina, also in the US, where Professor Daryoosh Vashaee created a device capable of capturing the temperature difference a human body and the external environment to transform into electricity.

The big problem of this modality is the amount of energy obtained by the device, always very low and unable to charge a cell phone. Thus, the method can be applied only to objects that are highly energy-efficient, and they consume very little energy.

From friction

There are also initiatives that study energy creation from material friction – triboelectric generation – as the small generator set up by Georgia Institute of Technology professor Zhong Lin Wang. In this method, the researchers developed a wearable device capable of obtaining energy from the movement and friction between objects.

Although any material causes friction, the right choice can result in an even more efficient method than the thermoelectric generation, says Wang. This type of technology could be implemented in technological clothing, but also in body sensors, greatly expanding its possibilities.

Unfortunately, though, it’s hard to imagine that such a novelty will be available in the short term – Wang believes it takes at least three years before his frictional energy generation system hits the market.

Until then, the great example of this branch is the Matrix PowerWatch, a watch that uses thermoelectric generation to function and was created from a collective financing project.

    Digital Technology has always been intimately linked to the human body. From sharpened flint to smart phones, we’ve been carrying our inventions for millennia—but I too believe that the relationship is about to get even closer, with the many innovative startups working to tap us for the energy to power this devices, it won’t take long. The next generation of electronic devices might not just be near our bodies, they could be powered by them. For years, our electronic devices have been getting smaller and faster, but the trend can’t continue until we solve one big obstacle: batteries. The human energy concept is promising. Using energy that would otherwise be wasted is appealing at a time when plans to fight climate change include using less energy or energy with lower carbon emissions. This means batteries that can pack more energy into smaller space or devices that could otherwise provide an energy boost without needing to plug into the wall. Staying alive guzzles energy. In order to keep us ticking, our bodies need to burn between 2,000 and 2,500 calories per day, which is conveniently enough to power a modestly used smart phone. So if just a fraction of that energy could be siphoned, our bodies could in theory be used to run any number of electronic devices, from medical implants to electronic contact lenses—all without a battery in sight. Recently, researchers have taken important strides toward unlocking this electric potential. And more is to come!!

    This is such a good post. Recharging Batteries With Body Energy may will not good for our health. Casio made a watch that have solar powered. Which are always on high-battery state and never become even mid-battery! Why we effect our health when we have solar power? I am not much familiar with this. Will recharging mobile devices effect our health?

    This is an interesting project that promises take advantage of the body’s energy for the development of the technological innovation. The energy of the human body can generate small amounts of electricity, and scientists believe it could be used in a large number of applications. Professor Steve Beepy, a researcher at the University of Southampton, is developing clothing made of materials capable of generating electricity by the heat of the body or by its movement. But not only that, the experts look for the form to generate electricity from the flow of our blood or the movement of the internal organs. A good example of this are pacemakers who take advantage of the heartbeat to function. The batteries of a pacemaker must be changed every seven years by surgery, if it is charged with the heartbeat the damages associated with an operation and its cost are avoided. Good post!

    In this era of innovation and technology , power remains to be an area where most machine manufactures have not yet been able to adventure fully and reduce the number of times one has to plug into the wall. The human body remains to be a diverse system which generates and would provide the necessary energy to do most of our tasks. With the creation of devices like the Matrix Power Watch it opens doors to many innovative ideas that can be turned into reality and help save in energy consumption and use of conventional batteries. The diversity in the forms of energy that can be acquired from the body like heat , friction ,pressure an interesting makes it an interesting and useful reality to the future users.
