However, since there is no fixed position for wearing the watch on the hand, especially a small wrist twist (non-movement) is not enough to cause the acceleration sensor to actuate, but this twist is enough to make the optical measurement signal error

Abstract

A portable device capable of compensating an action error to measure heatbeat information comprises a portable device body and a heartbeat information measuring system. The heartbeat information measuring system comprises an optical device and a piezoelectric device disposed on the portable device body. When the portable device body is worn, the optical device contacts a user's organic tissue to sense a physiological signal of the organic tissue and generate a photoelectric signal. The piezoelectric device detects a change, due to a user's action, of a pressure applied by the portable device body on the organic tissue, and generates a piezoelectric signal. The heartbeat information measuring system comprises a central processing unit, and, after the compensation operation is performed on the photoelectric signal according to the piezoelectric signal, the compensated photoelectric signal is converted into heartbeat information. A heartbeat information measuring method and the heartbeat information measuring system are also be provided, and then accuracy and stability of heartbeat information measurement are improved.

Description

technical field [0001] The present invention relates to a heartbeat information measurement, in particular to a portable device, a measurement method and a measurement system that can compensate movement errors to measure heartbeat information. Background technique [0002] It has been proved to be a feasible method to measure heartbeat by injecting light into skin tissue and detecting the contraction and dilation of blood vessels through the intensity change of reflected light; generally speaking, an optical device for measuring heartbeat contains several predetermined wavelengths When the LED illuminates a part of organic tissue, such as skin, the light is scattered / reflected in the organic tissue and partly absorbed, and the photoreceptor is used to detect Measuring the scattered / reflected light, as the blood flow pulse changes, the intensity of the scattered / reflected light will change, and the frequency of the change roughly corresponds to the frequency of the heartbeat...
