  • MEMS bubble generator
    Publication number: 20060250453
    Abstract: A MEMS vapor bubble generator with a chamber for holding liquid and a heater positioned in the chamber for heating the liquid above its bubble nucleation point to form a vapour bubble; wherein, the heater is formed from a superalloy.
    Type: Application

  • MEMS device with nanocrystalline heater
    Publication number: 20060250454
    Abstract: A MEMS vapor bubble generator with a chamber for holding liquid and a heater positioned in the chamber for heating the liquid above its bubble nucleation point to form a vapour bubble; wherein, the heater has a microstructure with a grain size less than 100 nanometres.

  • Self passivating transition metal nitride printhead heaters
    Publication number: 20060221135
    Abstract: A thermal inkjet printhead with heater elements formed from a self passivating transition metal nitride, but it oxidizes readily. By introducing an additive that allows the metal nitride to self passivate, the heater element forms a surface oxide layer, where the oxide has a low diffusion coefficient for oxygen so as to provide a barrier to further oxidation. With enhanced oxidation resistance, coatings to protect the heater from oxidative failure become unnecessary and the energy needed to form a bubble is reduced.
