Experimental research of the main static characteristics of the microfluidic trigger of the 100-micrometer feature size is carried out. In order to research the trigger, the experimental (physical) model has been especially made. As the main result of the research, the transfer and flow-rate characteristics of the trigger are obtained in relation to the two connection schemes: 1) the relay scheme with the two-input control, 2) the comparator scheme with the control at a first input and with a reference setpoint at a second input.
