Abstract
Provided are a filter element and a method of preparing a filter element. The filter element includes a pattern substrate having a first channel formed on one surface and a second channel formed on the other surface and including a first base and a second base which have different liquid permeabilities; a first liquid metal pattern disposed in the first channel; a second liquid metal pattern disposed in the second channel and at least partially overlapping the first liquid metal pattern; and a contactor configured to invade in the first base and the second base and electrically connect the first liquid metal pattern to the second liquid metal pattern.
Claims17
A filter element comprising:
- a pattern substrate having a first channel formed on one surface and a second channel formed on the other surface and including a first base and a second base which have different liquid permeabilities;
- a first liquid metal pattern disposed in the first channel;
- a second liquid metal pattern disposed in the second channel and at least partially overlapping the first liquid metal pattern;
- and
- a contactor configured to invade in the first base and the second base and electrically connect the first liquid metal pattern to the second liquid metal pattern.
A filter element comprising:
- a first base;
- a first passive element disposed on one surface of the first base;
- a second base disposed on the other surface of the first base and having liquid permeability that is greater than that of the first base;
- a second passive element disposed on the second base;
- a first contactor formed by a liquid metal invading in the first base and configured to be electrically connected to the first passive element;
- and
- a second contactor formed by a liquid metal invading in the second base and configured to be electrically connected to the first contactor and the second passive element,
- wherein an average width of the first contactor is greater than that of the second contactor.
A method of preparing a filter element, comprising:
- preparing a first pattern substrate having a first channel formed on one surface thereof and comprising a first base;
- forming a first liquid metal pattern in the first channel;
- preparing a second pattern substrate having a second channel formed on one surface thereof and comprising a second base;
- forming a second liquid metal pattern in the second channel;
- disposing the other surface of the first pattern substrate to face the other surface of the second pattern substrate;
- and
- pressurizing a portion of the first liquid metal pattern to form a contactor invading in the first base and the second base.
