Title: JET FLOW POWER CONTROL FOR OBJECT SORTING
Abstract:
A microfluidic actuator (100) for selecting objects in a fluid stream comprising a plurality of objects is described. The actuator (100) comprises an object detection means (101) adapted for, upon arrival of an object, identifying whether an object is an object of interest. It further comprises a heater (113) adapted for generating a jet flow for deflecting an object of interest from the fluid stream and a controller (104) for activating the heater (113) as function of the detection of an object of interest using a nucleation signal. The controller (104) is adapted for obtaining temperature information of the heater (113) and for adjusting a nucleation signal for the heater (113) taking into account the obtained temperature information.
