Abstract
The invention relates to methods and devices for control of an integrated thin-film device with a plurality of microfluidic channels. In one aspect, the present invention provides a method for controlling the temperature of a heater electrode associated with a microfluidic channel of a microfluidic device, wherein power applied to the heater electrode is regulated by varying the duty cycle of a pulse width modulation (PWM). In another aspect, the present invention a controller configured to compute the temperature of the heater electrode during the power-on portion of the duty cycle and the during the power-off portion of the duty cycle and to adjust the duty cycle as necessary to achieve a desired temperature in the heater electrode.
