  • Patent number: 8884382
    Abstract: A universal microelectromechanical (MEMS) nano-sensor platform having a substrate and conductive layer deposited in a pattern on the surface to make several devices at the same time, a patterned insulation layer, wherein the insulation layer is configured to expose one or more portions of the conductive layer, and one or more functionalization layers deposited on the exposed portions of the conductive layer to make multiple sensing capability on a single MEMS fabricated device. The functionalization layers are adapted to provide one or more transducer sensor classes selected from the group consisting of: radiant, electrochemical, electronic, mechanical, magnetic, and thermal sensors for chemical and physical variables and producing more than one type of sensor for one or more significant parameters that need to be monitored.

  • Patent number: 8795484
    Abstract: A printed gas sensor is disclosed. The sensor may include a porous substrate, an electrode layer, a liquid or gel electrolyte layer, and an encapsulation layer. The electrode layer comprises two or more electrodes that are formed on one side of the porous substrate. The liquid or gel electrolyte layer is in electrolytic contact with the two or more electrodes. The encapsulation layer encapsulates the electrode layer and electrolyte layer thereby forming an integrated structure with the porous substrate.

  • Patent number: 7679052
    Abstract: Methods of separating ionized particles comprise the step of providing a particle separator comprising a housing, and an electric field disposed inside the housing. The electric field defines a magnitude E (volt/cm) which increases the farther ionized particles travel within the housing. The method further includes delivering a gas flow, wherein the gas flow defines a velocity, Vgas, and delivering ionized particles into the housing, wherein the ionized particles define a mobility value, K (cm2/volt*sec). The product of the mobility value K and the electric field magnitude E define a mobility velocity for the ionized particles, Vmob (cm/sec)=K*E. The method also includes stopping the ionized particles at a location where Vmob is equal and opposite Vgas.
