One of the important problems of modern electronic implants are batteries, which must be removed and replaced after their expiration date. In addition, they are not very useful for the human body. However, scientists from the University of Illinois managed to develop nutrients that eventually dissolve in the human body, while leaving no toxic waste.
According to scientists, several versions of the battery have been developed, differing in the material from which the cathode is made. Tungsten, molybdenum, and iron were used as the cathode material, and magnesium served as the anode material. Electrolyte served as standard saline phosphate and sodium chloride, reports the portal medicaldaily.com.
Stage of dissolution of the battery
One square centimeter of such a battery, made of a magnesium anode with a thickness of 50 micrometers and a molybdenum cathode with a thickness of 8 micrometers, is capable of producing about 2.4 milliamperes of current. When the battery is dissolved, 9 milligrams of magnesium is supplied to the body.
The main problem of a soluble battery is a short time of its work, which so far is no more than a day. However, scientists are working to solve this problem.
According to scientists, devices with soluble batteries will be useful in medicine for creating implants, and for creating disposable chemical sensors that will dissolve without causing damage to nature.
