Non-invasive flexible blood glucose detecting and sleep monitoring device

A non-invasive flexible blood glucose detecting and sleep monitoring device for monitoring a sleep state and a blood glucose state of a detected person, the non-invasive flexible blood glucose detecting and sleep monitoring device comprising:

• a detection module, comprising:
• a substrate;
• a plurality of optical modules, each being an optical cover plate with a coating layer;
• retaining walls disposed on the substrate, the retaining walls respectively establishing a first space and a second space with the substrate and the optical modules;
• a light emitting unit disposed in the first space, the light emitting unit generating a first light and emitting the first light in a direction toward the detected person;
• and
• a sensing unit disposed in the second space, the sensing unit receiving a second light from the detected person, and the sensing unit generating a corresponding first signal according to the second light, wherein the second light is a reflective light of the first light;
• a flexible piezoelectric module for being placed on the detected person, the flexible piezoelectric module comprising:
• a first protective layer formed with a first blind hole for the detection module to be disposed in;
• a first electrode layer electrically connected to the substrate and receiving the first signal;
• a second electrode layer;
• a first piezoelectric layer disposed between a side of the first electrode layer and a side of the second electrode layer, the first piezoelectric layer inducing a piezoelectric effect therein to generate a second signal between the first electrode layer and the second electrode layer after bearing an external applied force;
• and
• a second protective layer disposed on the other side of the second electrode layer;
• and
• a detecting unit connected to the detection module and the flexible piezoelectric module, the detecting unit receiving the first signal and the second signal.
