Abstract

A test apparatus in which detectors and objects to be detected are rotated at the same speed, and a control method thereof are provided. The test apparatus includes a rotation driving unit that includes a rotary shaft; a microfluidic device that is loaded on the rotary shaft and includes at least one object to be detected; a rotating member that is mounted on the rotary shaft and includes at least one detector to detect the objects of the microfluidic device; and a controller configured to operate the rotation driving unit such that the microfluidic device and the rotating member are rotated at the same speed on the rotary shaft.

First claim

What is claimed is:

1. A test apparatus comprising:
a microfluidic device configured to be loaded on a rotary shaft of a rotation driving unit
and comprising an object in which a material to be tested by the test apparatus is received;
the rotation driving unit, which is configured to rotate the microfluidic device when the microfluidic device is loaded on the rotary shaft;
a rotating member that is directly mounted on the rotary shaft of the rotation driving unit and includes at least one detector to detect the object of the microfluidic device; and
a controller configured to operate the rotation driving unit such that the microfluidic device and the rotating member are rotated at the same speed on the rotary shaft.

2. The test apparatus according to claim 1 , wherein:
the controller is further configured to operate the at least one detector to detect the object when the rotation driving unit is operated, and to receive results of detection transmitted from the detector.

3. The test apparatus according to claim 2 , wherein the controller and the at least one detector communicate with each other via wired communication or wireless communication.

4. The test apparatus according to claim 3 , wherein the wired or wireless communication is selected from the group consisting of near field communication (NFC), BLUETOOTH, ZIGBEE, Wi-Fi, radio frequency identification (RFID), and universal serial bus (USB).

5. The test apparatus according to claim 1 , wherein the rotating member includes a printed circuit board (PCB) on which the at least one detector is mounted.

6. The test apparatus according to claim 1 , further comprising a slip ring that is mounted on the rotary shaft and supplies power to the at least one detector.

7. The test apparatus according to claim 1 , further comprising a power generation device that is mounted on the rotary shaft of the rotation driving unit and supplies power to the at least one detector.

8. The test apparatus according to claim 7 , wherein the power generation device comprises coils mounted on the rotary shaft and fixed magnets surrounding the coils.

9. The test apparatus according to claim 1 , wherein the at least one detector receives power supplied from a power supply unit wirelessly.

10. The test apparatus according to claim 1 , wherein the at least one detector comprises at least one of a camera and an optical sensor.

11. A control method of the test apparatus of claim 1 , the method comprising:
loading the microfluidic device on the rotary shaft of the rotation driving unit;
aligning the object of the microfluidic device with the at least one detector; and
operating the rotation driving unit such that the object and the at least one detector are rotated in alignment with each other at the same speed.

12. The control method according to claim 11 , further comprising operating the at least one detector to detect the object when the rotation driving unit is operated.

13. The control method according to claim 11 , wherein the aligning the object with the at least one detector includes positioning the object and the at least one detector opposite each other.
