Flexible PCB (Printed Circuit Board) based disposable skin surface dry electrode and manufacturing method thereof

Abstract

The invention discloses a flexible PCB (Printed Circuit Board) based disposable skin surface dry electrode and a manufacturing method thereof. The flexible PCB based disposable skin surface dry electrode used in the field of medical appliance comprises a flexible PCB base material and an electrode micro-needle array and a metal button respectively arranged on both the upper surface and the lower surface of the flexible PCU base material; a conducting medium for conducting the electrode micro-needle array and the metal button is arranged on the flexible PCB base material in a penetrating manner. According to the invention, the cost is low as the electrode micro-needle array is manufactured on the flexible PCB base material by adopting the matured electric plating technology rather than a micro-machining process technology, volume production is applicable as no hydrofluoric acid is used, the conform level of a user and the signal collection stability can be improved, and the skin electrode contact noise is reduced as the electrode manufactured on the flexible PCB rather than substrates such as silicon and metal is flexible and the electrode in use is directly attached to the skin surface of the user without pain and bleeding, and meanwhile the flexible PCB based disposable skin surface dry electrode is more convenient and faster to use as no skin pre-treatment is needed relative to a wet electrode.

Description

technical field [0001] The invention is used in the field of medical equipment, and in particular relates to a disposable skin surface dry electrode based on a flexible PCB and a manufacturing method thereof. Background technique [0002] Biopotential signals such as ECG signals, EEG signals, and EMG signals are very important for diagnosing human diseases and detecting human health conditions. The collection of these biopotentials is mainly obtained through the contact between the electrode and the human skin. It is self-evident that a good electrode can improve the quality of the collected signal. [0003] Today, the dominant electrode on the market is the wet electrode, the commercially available Ag / AgCl electrode. Because the outermost stratum corneum of the skin cannot conduct electricity, the wet electrode needs to be pretreated to corrode the stratum corneum or allow high-concentration conductive ions to penetrate the stratum corneum. Pretreatment methods include ...
