Abstract

The invention relates to a muscle impedance handheld electrode based on microneedle arrays. The muscle impedance handheld electrode comprises a hollow T-shaped handle and four microneedle array electrode plates; and the four microneedle array electrode plates are fixed to the bottom of the handle and connected with an external impedance testing device through four wires. The handheld electrode is used for intrusively detecting the muscle impedance in a painless manner; operation is easy and convenient; and the detection sensitivity is high.

Description

technical field [0001] The invention relates to the fields of microprocessing and medical equipment, and more specifically relates to a muscle impedance hand-held electrode based on a microneedle array and a preparation method thereof. Background technique [0002] Electrical impedance myography (Electrical impedance myography, EIM) uses a current electrode to apply a weak current to the muscle tissue area to be measured, and analyzes the voltage signal of the muscle tissue detected by the voltage electrode to extract and identify changes in muscle composition, structural damage, neuromuscular diseases, etc. Impedance characteristics closely related to the physiological state of muscles and their changing rules are non-invasive, cheap, safe, non-toxic, easy to operate, and rich in information. Using EIM to detect muscle impedance characteristics is useful in disease diagnosis, disease monitoring, drug efficacy evaluation, and rehabilitation. Guidance, personal care, etc. hav...
