WEARABLE PHYSIOLOGICAL MEASUREMENT DEVICE AND SIGNAL COMPARISON METHOD THEREOF

摘要

A wearable physiological measurement device worn on an arm of a body includes an electronic module, at least one strap body electrically connected with the electronic module, a first sensing module electrically connected with the processor module, and a second sensing module electrically connected with the processor module. An inside of the electronic module is equipped with a processor module. An inner surface of the strap body is flush with an inner surface of the electronic module. The first sensing module is fastened to the electronic module and is exposed to the inner surface of the electronic module to be close to a skin surface of an outer side of the arm. The second sensing module is fastened to the strap body and is exposed to an inner surface of the strap body to be closed to a skin surface of an inner side of the arm.

1. A signal comparison method of a wearable physiological measurement device, comprising the steps of:
a first optical sensor and a second optical sensor of the wearable physiological measurement device capturing and transmitting signals to a processor module of the wearable physiological measurement device; and the processor module comparing a first signal-to-noise ratio of the signal with a second signal-to-noise ratio of the signal, when the first signal-to-noise ratio is larger than the second signal-to-noise ratio, the processor module turning off a power of a second sensing module of the wearable physiological measurement device and calculating a first variation of photoplethysmography, or when the first signal-to-noise ratio is smaller than the second signal-to-noise ratio, the processor module turning off a power of a first sensing module of the wearable physiological measurement device, and calculating a second variation of photoplethysmography until a specific sensing time is over to terminate sensing.
