2003 – Passive Membrane Microvalves Patent – Motorola

In 2003, while working for Motorola Labs, I invented a novel micropump made from low temperature co-fired ceramic (LTCC) material. This unique design made use of a printed layer of glass for the sealing surface as well as laser cut silicone seals. A piezo electric disk was used as the actuator. A patent was filed by Motorola (US2004/0120836).
