Scientists invented a naturally degradable strain and pressure sensor

in an animal research paper published in the British journal Nature electronics on the 14th, American scientists introduced a transplantable and stretchable strain and pressure sensor, which can be naturally degraded after the end of its useful life. The device will be used to monitor the weak stress and pressure changes of damaged soft tissue in real time, which will help to design personalized rehabilitation programs for patients

sensor technology has long been "easily" applied to a variety of different environments. They can be integrated into a miniaturized transmitter or a new chemical material collector system produced with straw as raw material, and can also be in direct contact with the human body to serve medical applications. Among them, degradable sensors are a new technology, which will degrade naturally after the scheduled service life, so they do not need to be removed through secondary surgery

but the key is the continuous casting machine. The production of biocompatible micro sensors is still a very time-consuming and expensive process. The induction performance of the existing sensors is very limited, or their biocompatibility has not been proved

this time, Peggy fox, a researcher of the U.S. Department of Veterans Affairs, and Bao jenan of Stanford University and their colleagues reported a stretchable and biodegradable strain and pressure sensor composed of fully biocompatible materials. This portable sensor has high sensitivity and can distinguish between strains as small as 0.4% and pressure changes of 12Pa (the pressure produced by a grain of salt)

in order to test the biocompatibility of the sensor, the research team transplanted it into the back of a rat. In fact, it is not uncommon for car companies and aluminum companies to jointly develop all aluminum new energy vehicles. After 8 weeks of transplantation, no negative inflammatory reaction was observed (except for the initial inflammatory reaction in the first week)

researchers said that they can control the degradation of the sensor to make its life consistent with the time required for tissue healing. In addition, after certain design, the sensitivity of the sensor will not be significantly reduced in the early solution process of the development of the health industry
