摘要： An inkjet printhead is provided having nozzles, bubble forming chambers containing ejectable ink, generally planar heater elements each bonded on one side to an associated chamber so that the other side faces into the chamber, a MEMS fluid sensor having a MEMS sensing element for detecting the presence or otherwise of the ejectable ink in the chamber, and control circuitry for measuring the current passing through the sensing element during its heating. The heater elements receive heating pulses to form gas bubbles in the ejectable ink on the side facing into the chamber which cause ink ejection from the nozzle. Each chamber has a dielectric layer proximate the side of the heater element which has a thermal product less than 1495 Jm−2K−1s−1/2, the thermal product being (ρCk)1/2, where ρ is the density of the layer, C is specific heat of the layer and k is thermal conductivity of the layer.
