Super-micro implants

Medical electronic implants will become smaller and more powerful in the near future

DailyTechInfo based on ABM materials: Electrical engineers create tiny but powerful medical devices

Battery-powered medical devices implanted into the human body have already saved a huge number of human lives. Pacemakers that produce weak electrical impulses set a stable heartbeat rhythm in people with arrhythmia, and tiny defibrillators that generate more powerful impulses already allow you to avoid heart attacks and complete cardiac arrest in some cases. However, such devices also have a negative feature – their batteries require periodic replacement, which is associated with the risk of infection or surgical operations.

Mahdi Kiani, a scientist from the University of Pennsylvania, and his group are working to make electronic implantable devices smaller and having some functional features that allow you to get rid of the need to replace their batteries. "Now we are developing new methods of wireless power transmission and integrated power management technologies," says Mahdi Kiani, "and the dimensions to which we are trying to reduce the size of electronic devices are a millimeter or less, which also involves a lot of technical problems."

One of the key technologies, the development of which is almost completed, is the technology of adaptive integrated power supply management, operating in the mode of integrated current and voltage regulation. This mode provides a more efficient use of scarce energy than more traditional methods based only on the control of input and output voltage. And the capabilities of the new power management technology should be enough to power tiny devices powered by wireless technologies.

New devices that can be placed in almost any part of the human body will be able to collect and transmit data on the state of various organs to the outside, which will give doctors a more complete picture of the state of human health. In addition, something similar can be used to collect data from the depths of the human brain, which will allow scientists to study brain functions more deeply, determine the causes of certain diseases and find new effective methods to combat them.
