Abstract
There is provided a heating device to independently and/or effectively heat the micro objects manipulated by a micro apparatus/system, for example the droplets of fluids in an electrowetting on dielectric EWOD device of a microfluidic apparatus. The heating device may include a plurality of micro heaters arranged in an array of rows and columns, and the micro heaters of the heating device may be disposed in relative to the electrode elements of the EWOD device, respectively. Therefore, the micro heaters of the heating device may heat one of the electrode elements of the EWOD device, thereby preventing thermal effect of the micro object on the other electrode elements.
