According to the "Daily Telegraph" recently reported, researchers at Northwestern University have developed an electronic device implanted in the human body, which can be degraded according to the design procedure and absorbed by the body fluid, which helps the doctor to monitor the condition of the patient's body. Provide timely treatment options.
Electronic implants are not often used in surgery because of the fear of long-term retention of electronic implants in the patient's body, and most electronic devices may remain indefinitely. The soluble electronic device developed by the university consists of a millionth of a centimeter thick silicon and magnesium circuit that does not need to be removed from the body after it has functioned. This new implant is easily absorbed by body fluids and is harmless to the body.
The researchers found that by applying a circuit layer on silk proteins of different thicknesses, the time to circuit degradation can be accurately designed, ranging from a few days to a few months. They used the implant in a mouse experiment and observed that it was able to provide antibacterial drugs to the surgical wound and could be completely dissolved after almost 3 weeks.
The device will allow the doctor to monitor the condition of the patient, measure the patient's temperature and muscle activity, help identify problems such as post-operative infections, and provide timely treatment.
Professor Huang Yonggang (transliteration), the leader of the study, said: "When you need these electronic devices, they are there, and when they complete their mission to achieve our goals, they will disappear. This will be a new concept."
According to some experts, the technology can also be used to develop mobile phones and other devices, which can be programmed to be completely degraded after several years without being discarded and sent to landfills.
