Scientists from Zhejiang University and Cambridge University have developed electronic devices that can be absorbed by the human body.
If an electronic device can be implanted in a human body, performing physical signs monitoring, disease warning, wound healing tracking, etc., and transmitting the information wirelessly to a doctor or patient for follow-up, and then the devices are dissolved by human body fluids, Absorbs and expels without causing any side effects to the human body. It is conceivable that such electronic devices will play an unimaginable role in the diagnosis and treatment of diseases. In recent years, scientists have made great progress in building various degradable electronic devices using a variety of degradable materials such as DNA, proteins, degradable metals, etc. Degradable implantable electronic devices are far from our real life. The closer it is. The reporter recently learned from Zhejiang University that scientists at Zhejiang University and Cambridge University in the United Kingdom used egg white and degradable metals to create a memristor that can be dissolved and absorbed by human body fluids. Such electronic devices will play a role in the diagnosis and treatment of diseases. A memristor is an electronic device capable of realizing information storage. The reporter saw this new microelectronic memristor at Zhejiang University. A thin circular single crystal silicon substrate is neatly arranged with 16 white small square arrays. These white small squares are made of magnesium and tungsten thin film metal. Electrode. (a) Three-dimensional structure diagram of the degradable memristor based on egg white; (b) egg white and egg white dilution; (d) device electrical test results. The author of the paper, Associate Professor Wang Xiaozhi from the School of Information and Electronic Engineering of Zhejiang University, introduced that the core material of the 16 electrodes is a layer of 30 nm thick protein, so a memristor can store 16 bits of information. Researchers say that after the memristor is implanted in the body, it can perform physical signs monitoring, disease warning, wound healing tracking, and wirelessly transmit information to doctors or patients for follow-up. Experiments have confirmed that the degradable memristor can be read and written hundreds of times, and in dry conditions, the information can be stored for three months. When the memristor is placed in water or body fluids, the entire device dissolves almost completely in 3 days. The dissolution process of the device in water. According to Wang Xiaozhi, existing implantable medical devices generally contain non-degradable metal materials such as copper, gold, silver or aluminum. Implantation, replacement and removal require surgery. The emergence of degradable medical systems will likely make medical devices more compatible with the human environment, avoiding multiple implants at once. "It can be dissolved and metabolized by the human body, which means that it will not stay in the body for a long time and cause side effects to the human body." Wang Xiaozhi said. A related paper on the research was published online in the Journal of Applied Chemistry and Interfaces of the American Chemical Society. Wang Xiaozhi said that the research team will also use degradable materials to develop electronic devices such as artificial heart, artificial bladder, artificial skin, etc., to provide a technical basis for various electronic systems implanted in the human body in the future.
