The Gastric juice has a rather complex composition including hydrochloric acid (its major component), bicarbonate, pepsinogen and pepsin, mucus and the enzyme Factor castle. Present in the stomach acid is able to effectively decompose the food into separate components, but why not try to use it to produce electrical energy? Such was the task set itself, researchers from Massachusetts Institute of technology. In the end, they managed to create a working on the hydrochloric acid produced by the stomach.
This team of scientists for one year was engaged in the design and development of numerous devices that people may use for research purposes. For example, sensors that read heart rate or blood pressure in real time. One of the trends in the research was the attempt to automatically deliver drugs to specific parts of the human body. All these mechanisms work from tiny batteries, which not only was extremely expensive and could harm the body.
The New development of scientists replaces the traditional tiny battery-a galvanic element receiving energy from contained in the gastric juice hydrochloric acid. This supply was sufficient to operate the built-in generator temperature sensor for several days. And don't forget that this same energy device transmitted the received data wirelessly to a computer every 12 seconds.
While scientists are thinking about how to get the generator to work not only in the stomach but in the small intestine. After all, there is practically no acid, thus produced about 1% of the energy that the device generates in the stomach. However, the accumulated hydrochloric acid from energy is enough to ensure that the device worked for some time, periodically sending data to the outside of the body. The next stage of development is the optimization of the generator and its reduction in size, so you can combine it with several sensors.
many of you have Probably heard that the so-called sedentary lifestyle – that is, when a person is most of their time (usually at work) holds in a sitting position – very harmful to health.
Researchers at brown University located in Providence, United States created laboratory , which is then able to grow a network of blood vessels.
Many of us, the weather was caught off guard, whether it's a sudden downpour on the way home or to work, or the scorching sun in the absence of a beach or any shelter.
