Embodiment Construction

[0076] figure 1It is a schematic cross-sectional view of a wearable photoelectric sensing device disclosed in an embodiment of the present application. The wearable photoelectric sensing device 1a can be attached to the skin surface of a living body (for example: human) for biometric identification, or use photoplethysmography (Photoplethysmography; PPG) to detect physiological signals of a living body . Physiological signals are, for example, blood oxygen, muscle oxygen, brain oxygen, heart rate, blood pressure, lactic acid, atrial fibrillation, moisture, blood sugar, body temperature, and blood flow velocity. The wearable photoelectric sensing device 1 a includes a fabric layer 101 , a substrate layer 102 , a light emitter 103 , a plurality of light receivers 104 , a cover layer 105 , and a transparent material layer 106 . The substrate layer 102 is disposed on the fabric layer 101 . In one embodiment, the substrate layer 102 is a bendable flexible substrate. The coverin...

Abstract

The invention discloses a wearable photoelectric sensing device and a manufacturing method thereof. The wearable photoelectric sensing device comprises a fabric layer, a substrate layer, a light emitter, a plurality of light receivers and a covering layer. The substrate layer is arranged on the fabric layer. The plurality of light receivers are arranged on the surface of the substrate layer and form an array, and the light emitter is arranged at the geometric center of the array. The light receivers comprise a first light receiver and a second light receiver, the sensing wavelength of the second light receiver is larger than that of the first light receiver, and the distance between the second light receiver and the light emitter is larger than that between the first light receiver and the light emitter. The covering layer is arranged on the substrate layer, the covering layer comprises a plurality of holes, and the positions of the holes correspond to the positions of the light emitter and the positions of the light receivers.

Description

technical field [0001] The invention relates to a wearable device and a manufacturing method thereof, in particular to a wearable device with a photoelectric sensor and a manufacturing method thereof. Background technique [0002] Common health testing devices currently on the market include electronic products such as watches, bracelets, earphones, mobile phones, and portable testing devices. Although a variety of physiological data measurement technologies have been applied to various electronic products, the detection accuracy of these measurement technologies is still insufficient, resulting in the inability to correctly judge the real physiological status, which not only makes it difficult for some consumers to pay, but also fails to provide physicians with reliable data as a reference for diagnosis. Therefore, considering the future development trend of medical devices, how to effectively improve the signal-to-noise ratio of the detection device is an issue that must ...
