Researchers at the Massachusetts Institute of Technology have developed a new technology that uses radio waves to charge implanted devices in the human body. It is expected to be used in in vivo administration and monitoring of physical conditions.
The Massachusetts Institute of Technology recently issued a press release saying that researchers used radio waves that penetrate the body tissue safely in animal experiments to charge a device that was buried 10 cm below the pig's skin at a distance of 1 meter. If the device is shallow The layer can be wirelessly charged up to 38 meters away. The researchers say that the prototype device used in the experiment is only the size of the rice grain, and can even be made smaller, swallowed or implanted into the body.
MIT Assistant Professor Fadler Adib said that the implant device does not use traditional batteries to help develop new medical uses. In August this year, he will report this at the American Computer Society's Data Communications Professional Task Force meeting. A new technology.
However, the challenge of using radio waves to charge devices in the body is that radio waves can wear out when they penetrate the body. To this end, researchers have designed a system in which a group of antennas emit radio waves of different frequencies that are propagating. Overlays occur during the process, allowing the implant to get enough power.
According to the researchers, when charging, because the radio wave coverage area is large, there is no need to accurately position the sensor in the body, which means that multiple devices can be charged at the same time.
In addition, the in-vivo sensor receives the command signal and transmits the collected information back to the antenna. Therefore, the system can be used for in vivo administration, monitoring of physical conditions, etc. Researchers say, further improve the set. After the wireless charging system, it is expected to be used in more fields requiring long-distance communication and tracking.
