Integrated Molecular Sensor System

摘要

An embodiment includes a package comprising: a cavity formed in a dielectric material; a beam in the cavity; an interconnect to couple the beam to a current source; a magnet coupled to the cavity; and a polymer, on the beam, having an affinity to an analyte; wherein (a) a vertical axis intersects the magnet, the cavity, and the beam; (b) in a first state the beam and the polymer, which is not coupled to the analyte, collectively have a first mass and resonate at a first resonant frequency when the beam conducts a first current; and (c) in a second state the beam and the polymer, which is coupled to the analyte, collectively have a second mass that is greater than the first mass and resonate at a second resonant frequency when the beam conducts a second current. Other embodiments are described herein.

1. An electronic package, comprising:
a cavity formed within a dielectric material; a beam located in the cavity and having a long axis in a horizontal plane; an interconnect to couple the beam to a current source; a magnet coupled to the cavity; and a polymer, on the beam, having an affinity to a chemical analyte; wherein (a) a vertical axis intersects the magnet, the cavity, and the beam; (b) in a first state the beam and the polymer, which is not coupled to the chemical analyte, collectively have a first mass and resonate at a first resonant frequency when the beam conducts a first current from the current source; and (c) in a second state the beam and the polymer, which is coupled to the chemical analyte, collectively have a second mass that is greater than the first mass and resonate at a second resonant frequency, unequal to the first resonant frequency, when the beam conducts a second current from the current source.
