Description

technical field [0001] The invention belongs to the technical field of medical devices, in particular to a medical flexible integrated electrode. Background technique [0002] Due to the development of modern diagnosis and treatment technology, electrophysiological detectors in various application fields are continuously introduced, especially the further development of hand-held and portable medical equipment, and the requirements for sensors (electrodes) are also different. From recording a set of waveforms to recording human body surface potential maps, dozens or even hundreds of electrodes need to be installed. The feedback circuit with electrodes and cables is time-consuming and complicated to install individually. It requires better integration of electrodes and feedback circuits for integrated placement. Due to the different shapes of different parts of the human body and the ups and downs, it is required that the placed electrodes can be in good contact with the bod...
