This week’s Science-Transformation Medicine magazine published a medical achievement jointly developed by Northwestern University, University of Illinois at Urbana-Champaign and the University of Pennsylvania, which uses a new type of flexible silicon electronics. The device can not only flex and stretch at will, but also detect the patient's ECG changes in a more detailed manner. Compared with the traditional detection device, it can more accurately monitor whether the patient has arrhythmia. And other symptoms.
One member of the research team, Yonggang Huang, an engineering professor at Northwestern University, said: "The heart is an organ with a shape that is constantly changing and has irregular appearance. The traditional electrical equipment used to detect the heart state is more suitable. Detecting electrical signals from flat, regular organs. The new device we developed this time can be wrapped in irregularly shaped organs and the material is stretchable, making it ideal for use in the detection of organs such as the heart. â€
The test equipment has been tested on animal organs. The test equipment is only 14.4 x 12.8 mm square, and the size is about the same as a five-cent coin, but it has 288 contacts and more than 2000. Transistors, by contrast, traditional ECG devices typically have contacts of about 5-10.
The increased number of contacts allows the sensing device to be more in contact with the heart, which results in a better and more detailed ECG. However, at present, such devices are not able to achieve wireless connectivity. Scientists say that the next research plan is to make this device self-generating, and the ideal power source is of course to use the pacing effect of the heart itself.
