Patent number: 10466190Abstract: An apparatus and method for producing chemielectric point-sensor systems with increased sensitivity and increased selectivity. The chemielectric sensor system includes a sensor/heater assembly, where the sensor is a chemielectric sensor whose resistance or capacitance changes upon exposure to chemical analytes. The heater functionality applies a programmed sequence of one or more thermal pulses to the sensor to quickly raise its temperature. After each thermal pulse ends the change in resistivity of the sensor is measured. Such data as a function of the pulse time and temperature are recorded and analyzed to determine the chemical composition (selectivity) and concentrations in the ambient vapor by comparison to a library dataset. The sensor operation with fast thermal pulses also allows operation at higher frequencies where the noise is lower and hence sensitivity is improved.Type: GrantFiled: September 24, 2018Date of Patent: November 5, 2019Assignee: The Government of the United States of America, as represented by the Secretary of the NavyInventors: Mario Ancona, F. Keith Perkins, Arthur W. Snow

Patent number: 9157842Abstract: A molecular concentrator comprising a thermal ratchet for driving molecules from one place to another. A plurality of linear, two-dimensional, and/or three-dimensional arrangements of heater structures are arranged on or suspended above a substrate. Each of the heater structures is configured to strongly sorb a vapor of interest when the heater structure is at room temperature and to rapidly desorb the vapor when the heater structure is at an elevated temperature. The vapor sorption of the individual heater structures is made selective by surface treatments, by monomolecular film depositions or by thicker absorbent polymer depositions. By selectively heating and cooling the heater structures, vapor molecules incident on the heater structures can be directed in a desired manner, e.g., from heater structures closest to a vapor-containing environment to a sensor.Type: GrantFiled: February 5, 2015Date of Patent: October 13, 2015Assignee: The United States of America, as represented by the Secretary of the NavyInventors: Mario Ancona, Arthur W.
