Description

A kind of Subminature multifunctional high accuracy physiology electric harvester

Technical field

The invention belongs to biomedical technology and wearable device field, be specifically related to a kind of Subminature multifunctional high accuracy physiology electric acquisition module that can gather electrocardio, myoelectricity and brain electricity.

Background technology

Wearable computer is a kind of new ideas, superminiature, wearable computer system, owing to can " dress " on human body, so can realize man-machine between nature, convenient and directly mutual, make people can carry computing equipment in a more natural way and obtain computing function, finally realize man-machine between " best combination and collaborative ".Predict according to authoritative department, wearable science and technology can be the next opera involving much singing and action on market, following 3 or five years market values will develop into about 50,000,000,000 dollars from today 30 ~ 5,000,000,000 dollars, market potential very huge (Wei Baozhi. hot spot technology patent prewarning analyze (wearable computing equipment fascicle) [M]. Beijing: Intellectual Property Publishing House, 2014,1).

On the whole, the main product form in Chinese wearable device market is based on intelligent watch, and bracelet, necklace etc. are auxiliary, and function is distributed in amusement and leisure and body-building, medical treatment & health field, and enterprise is many in a line city such as Beijing, Shenzhen.The academy's prediction of speed way, sport and body-building, medical treatment & health by become give priority to segmentation field (Ji Jing. speed way academy: the wearable device market analysis [EB/OL] .http in 2013: //www.sootoo.com/content/467072.shtml, December 6 days, 2013).But, traditional medical electronics because bulky, power consumption is very high cannot be embedded in the middle of wearable device well.

Market there are some have the wearable healthy equipment of intention and value, such as, Zephyr BioModule body-building clothes and brainlink idea head hoop.Zephyr BioModule body-building clothes chest locations has a circular biological sensor (BioModule), an accelerometer can monitoring action and speed is had in this biological sensor, can measure the heart rate of user, breathing rate and skin temperature (Wei Baozhi. hot spot technology patent prewarning analyzes (wearable computing equipment fascicle) [M]. Beijing: Intellectual Property Publishing House, 2014,10-11).Brainlink idea head hoop is a wearable device based on single channel EEG signals that grand intelligence Science and Technology Ltd. of Shenzhen releases, and user can carry out some training and operation by it.But these wearable healthy equipment are most not based on electro-physiological signals exploitation, but electro-physiological signals possesses great meaning in medical diagnosis on disease.Even if there is fraction equipment to be that these equipment also can only gather the electro-physiological signals of 1-2 passage, and this cannot meet the requirement of wearable device for medical diagnosis on disease based on electro-physiological signals exploitation far away.Why occurring such situation, be that not only amplitude is small because of electro-physiological signals, and frequency is very low.Therefore, to the restriction of various noise and drift characteristic and require just very strict (Yu Xuefei. modern medicine electronic machine principle and design [M]. Guangzhou: publishing house of South China Science & Engineering University, 2007,8).And on market existing physiology electric acquisition module not only bulky, power consumption is very high but also result of use can not meet the requirement of people completely, this does not meet wearable device miniaturization, low-power consumption, high performance requirement, and commercially quantity is few to result in the wearable device developed based on electro-physiological signals.
