A wearable physiological state detecting device includes an elastic ring body, an inflatable bladder, a detecting module and a wireless transmission module. The elastic ring body has a containing space that the inflatable bladder, the detecting module and the wireless transmission module are contained therein. The detecting module has a driving unit, a processing unit, a radiating unit and a receiving unit. The radiating unit generates a first light beam and a second light beam. The receiving unit receives the first light beam and the second light beam to generate a feedback signal. The processing unit receives the feedback signal to generate a measuring signal. The wireless transmission module receives and delivers the measuring signal.一種穿戴式生理狀態量測裝置包括一環形彈性本體、一氣囊、一量測模組以及一無線傳輸模組。環形彈性本體具有一容置空間,其係容置氣囊、量測模組以及無線傳輸模組。量測模組具有一驅動單元、一處理單元、一發射單元及一接收單元。於一工作期間,發射單元係發射一第一光束及一第二光束,而接收單元係接收第一光束及第二光束後產生一回授訊號,處理單元係接收回授訊號並據以產生一量測訊號,無線傳輸模組則係接收並傳送量測訊號。1‧‧‧穿戴式生理狀態量測裝置10‧‧‧環形彈性本體102‧‧‧外週緣103‧‧‧內週緣11‧‧‧氣囊13‧‧‧無線傳輸模組14‧‧‧充氣泵LE1‧‧‧第一發光元件LE2‧‧‧第二發光元件RE1‧‧‧光接收元件
