1. A reflective sensing module, comprising:
- a top cover which is transparent;
a first bottom circuitry on a bottom surface of the top cover;
a light chip having first top electrodes on a top surface of the light chip, the first top electrodes being physically attached and electrically coupled to the first bottom circuitry; and
a sensor chip having second top electrodes on a top surface of the sensor chip, the second top electrodes being physically attached and electrically coupled to the first bottom circuitry;
whereinthe light chip is configured to emit light beams upwards passing through the top cover to an object, andthe sensor chip is configured to detect light beams reflected downwards from the object and passing through the top cover for a further processing.

Abstract
A reflective sensing module is disclosed which can be embedded in a wristband for sensing a health information of a person wearing it. The health information can be wireless transmitted directly or indirectly to the internet for a further process. The reflective sensing module comprises a top glass, a bottom circuitry configured on a bottom surface of the top glass, a light chip and a sensor chip are electrically coupled with the bottom circuitry of the top glass; wherein the light chip emits light beams upwards passing through the top glass to an object; the sensor chip detects reflective light beams downwards passing through the top glass for a further process.
