Abstract
According to an exemplary embodiment of the present disclosure, a pressure sensing device using a sensor based on a Wheatstone bridge includes: a half Wheatstone bridge unit including two variable resistors of which resistance values are changed according to an environmental change; a variable capacitor unit electrically connected to the half Wheatstone bridge unit and generating RC delays for two variable resistors, respectively; an amplifier amplifying respective charging voltages charged after a time of the respective RC delays; and a comparator comparing the amplified charging voltages and outputting the compared charging voltages as digital values. As a result, an intraocular pressure sensing device is further miniaturized and has smaller power loss.
