Wristband-type biological signal acquisition equipment and manufacturing method thereof

Abstract

The invention provides wristband-type biological signal acquisition equipment and a manufacturing method thereof. The equipment comprises a wrist strap, a micro-needle array formed on a micro-needle array substrate and a biological signal output interface, the micro-needle array is fixed on the wrist strap and is in contact with the wrist skin of a wearer, and the biological signal output interface is connected with electrodes of the micro-needle array to output acquired biological signals. The wristband-type biological signal acquisition equipment provided by the invention is low in cost, simple to use, convenient to carry, safe and comfortable, and a user can continuously and stably record static and moving biological signals after wearing the equipment for a long time.

Description

technical field [0001] The invention relates to the technical field of biological signal collection, in particular to a wristband-type biological signal collection device and a manufacturing method thereof. Background technique [0002] The monitoring of biological signals, including electromyography (EMG) and electrocardiography (ECG), is an important means for early diagnosis of human health and diseases in various biomedical fields. EMG monitoring can be used in the diagnosis of neuromuscular diseases, the detection of muscle motor function, and the control of artificial limbs; and the analysis of heart rate variability (heart rate variability, HRV) by recording ECG signals can be applied to cardiovascular diseases (hypertension, myocardial infarction, etc.) , prediction of sudden cardiac death, coronary heart disease, congestive heart failure, etc.) [0003] At present, the acquisition of bioelectrical signals must require electrodes and acquisition systems, but the tra...

Problems solved by technology

[0005] For the production of microneedle array electrodes, the classic photolithography and etching techniques need to use sophisticated equipment in a clean room and are prone to produce toxic waste, which is inconvenient, expensive and not environmentally friendly; the laser processing method is efficient and flexible, but using pure The biocompatibility of copper materials needs to be considered. For high-density and small-sized microneedles, laser focusing may not be achieved; 3D printing technology is flexible but also not suitable for high-density and small-sized microneedles

The existing technology simply shows that microneedle array electrodes can be used to collect bioelectrical signals, but there is no complete wearable system based on array electrodes, and the wearing of electrodes still needs to be fixed with adhesive tape, which is sensitive to some skin. users is still a problem
