Wearable card sticker capable of acquiring human voice signal

Abstract

The invention discloses a wearable card sticker capable of acquiring a human voice signal. The wearable card sticker comprises a flexible shell, a flexible cell and a flexible circuit module, wherein the flexible shell is arranged to be suitable to be directly attached to a skin surface or attached to the inner side of clothes so as to enable a sound sensor to be tightly contacted with the skin; the sound sensor converts a vibration signal into an electric signal; an analog sensor interface is connected with the sound sensor; the electric signal is transmitted to an analog filtering module; the analog filtering module performs filter conditioning on the electric signal and amplifies the signal so as to meet the requirement of A / D (Analog / Digital) sampling; a microprocessor circuit control module controls to perform A / D sampling; the processed data is wirelessly transmitted to an upper computer by a wireless transmission module; and a power supply module supplies power to the flexible circuit module. The wearable card sticker is attached to the human skin surface or connected onto the inner side of the worn clothes, so that human voice signals at various parts can be detected and processed, and the wearable card sticker has high portability and can carrying out real-time detection.

Description

technical field [0001] The invention relates to a wearable sticker for collecting body sound signals. Background technique [0002] The sound signal of the human body carries a large amount of human health information. For example, a doctor can judge whether a patient's cardiovascular and lung functions are healthy and perfect through the heart sound and lung sound. [0003] The traditional detection method requires the patient to go to the hospital for auscultation intermittently, and then the doctor judges the specific situation of the patient. This method is not forward-looking and cannot remind the patient's condition in daily life; at the same time, the patient needs to wait in the hospital remotely. with check. [0004] Existing medical detection equipment requires patients to stay in the hospital for a long time, and special instruments cannot be continuously detected, so it is difficult to accurately locate the disease; it is difficult for traditional stethoscopes t...

[0003] The traditional detection method requires the patient to go to the hospital for auscultation intermittently, and then the doctor judges the specific situation of the patient. This method is not forward-looking and cannot remind the patient's condition in daily life; at the same time, the patient needs to wait in the hospital remotely. with check

[0004] Existing medical detection equipment requires patients to stay in the hospital for a long time, and special instruments cannot be continuously detected, so it is difficult to accurately locate the disease; it is difficult for traditional stethoscopes to recognize relatively subtle sounds, and doctors in the process of auscultation It will also be disturbed by the environment; in addition, there are some joint sounds and pulse sounds of the human body that cannot be monitored by the current auscultation system. Such signals are also of medical value in medicine
