    摘要： Systems and methods for in vivo sensing are provided. An excitation signal is produced, having a first frequency component and a second frequency component. The first frequency component is swept through a plurality of excitation frequencies within a frequency range of interest.. A response signal is received from an in vivo sensor. The response signal includes a mix component having a frequency equal to one of a sum of a first excitation frequency associated with the first frequency component and a second excitation frequency associated with the second frequency component and a difference between the first and second excitation frequencies. The mix component is evaluated to determine a resonant frequency of the in vivo sensor.

    摘要： The present invention provides a MEMS-based integrated particle identification system having a substrate, a magnetic structure, and a bioferrograph. The substrate includes a topside portion, backside portion and a flow system. The flow system includes a flow channel for accepting the flow of a stream of particles to identified. The magnetic structure is in physical communication with the topside and backside portions of the substrate and has at least two pole pieces. A plurality of pole piece embodiments are provided for generating a magnetic field that acts on magnetically susceptible particles in the flow stream. The bioferrograph has at least one sensor for identifying the presence and quantity of magnetically susceptible particles. A plurality of sensor embodiments are also provided.

    摘要： An implant includes a plurality of parallel layers spaced apart by a plurality of members. Each layer has a substantially uniform thickness between opposite surfaces and a plurality of openings that permit fluid flow through an interior of the implant defined by the layers. The surfaces of each layer includes an array of micro-structures. Each micro-structure has a substantially uniform shape and an average height of about 1 nm to about 20 μm.
