Biobatteries tattoos for obtaining energy from Technology

In the future, sweating, we will benefit not only, but also the small electronic devices eating liquid from our organism. Scientists reported that created the sensor in the form of a temporary tattoo which is capable to watch physical activity of the carrier and to develop energy from its sweat.

As reports PhysOrg, new development is one of about 12 000 works presented within the 248th National assembly and an exhibition of the American chemical society (ACS). The principle of operation of the device consists in detection and response to salt of dairy acid (lactate) as a part of sweat.

On level of a lactate it is possible to judge intensity of trainings. The more physical activities tests an organism, the more it allocates this salt. At physical activity the organism needs additional energy which is generated in process гликолиза. As a result of splitting of carbohydrates (mainly glucose) energy and a lactate which is found in blood is liberated.

To supervise lactate level in blood it is peculiar to professional athletes. However the usual control method is inconvenient, as samples need to be collected at different times during all training, and after to analyze.

Researchers from the Californian university in San Diego developed more effective method of measurement of level of a lactate at performance of intensive physical exercises. They put the flexible sensor of salt of dairy acid on paper for a temporary tattoo. The sensor contains enzyme which selects electrons at a lactate, generating a small electric current. The device was tested on 10 healthy volunteers.

Can sweat power your smartphone? Researchers in California have developed a device that can monitor your workout progress and generate power from your perspiration. Dr. Joseph Wang and his team at UC San Diego showed off their invention at the national meeting of the American Chemical Society in San Francisco. It works by measuring a chemical called lactate that is naturally present in sweat. The more intense the workout, more lactate your body produces. The sensor also strips electrons from lactate to generate a small electrical current. Wang hopes the device can eventually power a smart watch or heart rate monitor.

Then, relying on the received results, scientists decided to create the biobattery, capable to be charged from sweat. Experiment with participation of 15 volunteers showed that less sports people allocate more energy, than those who visits the sports hall at least three times a week. Researchers explain it so: those who goes in for sports less often, quickly are tired of physical activity and start to sweat more plentifully, starting process гликолиза, being accompanied formation of dairy acid. So, from one square centimeter of skin of the person unprepared to sports scientists managed to collect the 70th microwatt of energy.

It is not a lot of, but there is quite enough for maintenance of work of the electronic clock consuming all the 10th microwatt of energy. Researchers plan to improve technology to receive even more energy and to find a way of its preservation.

Biobatteries possess a number of advantages in comparison with ordinary batteries: they are quicker recharged, use renewables and are safer for the nature and the person as do not allocate toxins and do not blow up. Such devices have wide potential of application, scientists note.

Earlier scientists suggested to charge smartphones dew.
