The development of technology has allowed that today flexible devices can be manufactured that do not suffer any type of breakage when bending. However, these devices use conventional batteries that have to be recharged. It seems that this problem could be solved after a group of scientists have developed a battery model that is flexible, elastic, soft and that works with human sweat.
Its dimensions are two centimeters both in length and width. Therefore, it is a size that makes it very dynamic and very comfortable to use. The battery is printed under a fabric that is responsible for absorbing sweat.
Generates electricity by absorbing sweat
There are different companies and universities around the world that are also developing their flexible battery models that work with human sweat.
This fabric can accommodate some parts of the body. Therefore, we could comfortably carry this battery to recharge our Smartwatch when, for example, we go out to do sports or run.
It is essential to do this type of task while you carry the battery, since when you carry out this type of activity you sweat and that allows the battery to feed thanks to its absorbent fabric.
The battery is made up of a water-attracting element and silver “flakes”. When these components are exposed to sweat, a chemical reaction occurs that generates electricity. The test that was done to check the operation of the battery was to place it on the wrist of a volunteer who began to do an exercise bike for thirty minutes.
The results were that a voltage of more than 4 volts and an output power of almost 4 milliwatts was generated, which was more than enough energy to power a temperature sensor that was continuously sending data to a Smartphone through a connection. Bluetooth.
Comfortable, small and does not pollute
Another advantage of this new battery is that it is not made with any chemicals or heavy metals , something that is of great importance when it comes to recycling.
As the main head of the group of scientists assures, this new battery could be more durable than today’s technology , since it can withstand all the effort and activities that a person does throughout the day, in addition to being exposed to sweat.
In addition, its flexible design and small size allow it to accommodate the user with that subtle design.
