Abstract

The invention discloses a microneedle array dry electrode based on a flexible substrate and a preparation method of the microneedle array dry electrode. The method includes the steps that needle tipsof metal microneedles are inserted downwards into a base with a plurality of micro-through holes which are not connected with one another to form a microneedle array; the needle tips of the arranged microneedle array are placed upwards in a groove, and a conductive prepolymer is added into the groove to be solidified and molded into the flexible conductive substrate; and the substrate with the micro-through holes is separated from the conductive microneedle array, and the microneedle array dry electrode based on the flexible substrate is obtained. The microneedle array dry electrode includes the metal microneedle electrode array and the flexible conductive substrate, and the flexible conductive substrate is combined with the metal microneedles to prepare the microneedle dry electrode; andthe preparation method is simple, the cost is low, the microneedle electrode strength is high, the safety is high, long-time and high-efficiency signal acquisition is realized advantageously, and themicroneedle array dry electrode can be widely applied to the technical field of medical apparatus and instruments.

Description

technical field

[0001] The invention relates to the technical field of medical devices, in particular to a microneedle array dry electrode based on a flexible substrate and a preparation method thereof. Background technique

[0002] Physiological electrical signals mainly include myoelectricity, electrocardiogram, electroencephalogram, oculoelectricity and other signals, which can directly reflect the health status of a person and play an important role in medical diagnosis. It is the main monitoring object and physiological index basis in the process of clinical medical diagnosis, and has important guiding significance for the diagnosis and treatment of clinical diseases such as cardiovascular and cerebrovascular diseases and muscle dysfunction. Since physiological electrical signals are weak electrical signals, especially for ECG signals, which are about 1-100 μV, they are easily affected by noise, movement, etc. during the measurement process. Therefore, biomedical elect...
