Abstract

The invention relates to a wearable flexible sensor, in particular to a flexible and attachable sensor used for neck pulse detection. The flexible and attachable sensor comprises a fabric substrate, a sensitive layer, an electrode layer, an isolation layer and a protection layer; the isolation layer is arranged on the fabric substrate, the sensitive layer is arranged on the isolation layer and is of a high-sensitivity three-dimensional hole structure, the electrode layer is located between the sensitive layer and the protection layer, and the protection layer is used for being attached to the surface of the part, corresponding to the pulse part, of the skin of the neck of the human body. As sensitive materials are good in stability and biocompatibility, a stable whole is easily formed on clothes or dress accessories. The sensor is light, thin and soft, can be machined to be in various shapes, can be attached to or worn on the surface of the skin, has the advantages of being low in cost, simple in process, high in sensitivity, comfortable to wear, capable of being washed and the like, and can achieve continuous and dynamic detection on physiological parameters of the pulses of the neck of the human body for a long time. The invention further provides a manufacturing method of the sensor. The method is simple and easy to operate.

Description

technical field [0001] The invention relates to a wearable flexible sensor, especially a flexible attachable sensor for neck pulse detection and a preparation method thereof. Background technique [0002] The human neck pulse signal contains important physiological parameters. Medical research has shown that peripheral carotid body chemoreceptors play an important role in mediating signal changes such as hypoxemia, hypercapnia and acidosis. The activity of chemoreceptors and their reflex sensitivity are significantly increased in disease states, such as patients with hypertension, sleep-disordered breathing (including obstructive sleep apnea), and congestive heart failure, as well as in animal disease models. The carotid body maintains the body's blood oxygen stability under physiological conditions, and participates in the development of diseases under pathological conditions. The cellular and molecular regulatory mechanisms of the carotid body can be used to explain the ...
