Massachusetts Institute of Technology (MIT) as the world's top institutions of higher learning, always can introduce many novelties. Although some things may seem overly weird, most of the time, their research results are of high practical value. Today, many times in order to be able to better check the patient's condition, the hospital usually uses an implantable method to connect the sensor directly to the human skin. And MIT has developed a more advanced device in the near future because it can be "ate" by the patient. The device has been approved by the U.S. Food and Drug Administration (FDA) and patients can swallow the sensor like a capsule. Therefore, it is also called "camera pill". In the human body, it can not only transmit high-definition video to show the most clearly the patient's gastrointestinal situation, but also can calculate heart rate and respiratory rate through other sensing functions, To better detect heart and lung function. At the same time, electronically processing the audio collection function in this device can effectively distinguish heart sounds and lung sounds so that doctors can obtain more clear information. Researchers hope to use more advanced sensors to obtain more information in the patient's body, to provide them with more and better treatment programs to promote the progress of the entire medical career.
