1. A pumpless wearable sphygmomanometer, comprising:

  • a wearable element;

    a first fluid strip, disposed on a first side of the wearable element, wherein the first side is for contacting with a wearer;

    a second fluid strip, disposed on the first side, wherein the first fluid strip and the second fluid strip are arranged in parallel and spaced apart for a predetermined distance; and

    a control module, disposed on the wearable element and comprising;

    a first pressure sensing element, communicating with the first fluid strip and configured to sense a first fluid pressure in the first fluid strip;

    a second pressure sensing element, communicating with the second fluid strip and configured to sense a second fluid pressure in the second fluid strip; and

    a processing unit, electrically connected to the first pressure sensing element and the second pressure sensing element, wherein the processing unit is configured to analyze a difference between the first fluid pressure and the second fluid pressure and to issue an operating instruction, and the operating instruction comprises;

    prompting the wearer to exert a force on the wearable element and thereby pressing against the first fluid strip and the second fluid strip; and

    prompting the wearer to gradually release the exerted force when both of the first fluid pressures and the second fluid pressure are greater than a predetermined value and, concurrently the difference between the first fluid pressure and the second fluid pressure falls within a predetermined range.
