Publication number: 20230324340Abstract: Disclosed herein is a chemical sensing system, comprising: a sensor configured to adsorb an analyte; an electronic circuit to operate the sensor; and a microcontroller in communication with the sensor and the electronic circuit. The microcontroller can also be configured to provide a real-time signal indicative of a concentration of the analyte. The sensor can comprise a microelectromechanical system (MEMS) resonator and a sensing film configured to adsorb the analyte, the sensing film coating at least a portion of the sensor. The MEMS resonator can comprise a second sensor, such as an impedimetric sensor to measure at least a second property of the sensing film. The electronic circuit can process signals stemming from at least two properties of the same sensing film, such as the changes in mass and dielectric constant of the same sensing film due to adsorption of analyte.Type: ApplicationFiled: June 5, 2023Publication date: October 12, 2023Inventors: Luke Armitage Beardslee, Oliver Brand, Kemal Safak Demirci, Jae Hyeong Seo, Steven Andrew Schwartz

Publication number: 20220326610Abstract: In a method making a flexible electrical conductor, a mask layer (216) is applied to a substrate (210). A portion of the mask layer (216) is removed to expose the substrate (210) in an exposed shape (220) corresponding to the conductor. A liquid phase conductor (232) is applied to the portion of the substrate (210). The mask layer (216) is dissolved with a solvent (238) to leave a shaped liquid phase conductor (234) corresponding to the exposed shape on the substrate (210). A primary elastomer layer (240) is applied onto the substrate (210) and the shaped liquid phase conductor (234). The primary elastomer layer (240) and the shaped liquid phase conductor (234) are removed from the substrate (210). A secondary elastomer layer (242) is applied to the shaped liquid phase conductor (234) and the primary elastomer layer (240) to seal the shaped liquid phase conductor (234) therein.Type: ApplicationFiled: June 21, 2022Publication date: October 13, 2022Inventors: Mingu Kim, Oliver Brand, Devin K.

Patent number: 7696749Abstract: The resonator-based magnetic field sensor system has an oscillatory member as resonator, means for driving an electrical current through said resonator such that its resonance frequency is altered by an external magnetic field to be measured (measurand), and means for detecting or measuring said altered resonance frequency. A secondary excitation of the resonator is effected to determine the said altered resonance frequency from which the measurand can be deduced. In the preferred embodiment, the secondary excitation is included in a closed loop, thus creating an oscillator vibrating at the altered resonance frequency. Though it is known to use the oscillation amplitude of a suitable resonator for this purpose, the novel sensor system identifies and/or measures the frequency (not the amplitude) of the oscillation, which is a function of the magnetic field to be measured.Type: GrantFiled: August 22, 2005Date of Patent: April 13, 2010Assignee: Sensirion Holding AGInventors: Robert Sunier, Oliver Brand, Tobias A.

Patent number: 6668627Abstract: A magnetically excited, resonant cantilever sensor apparatus has a cantilever as the transducer element. A static magnetic field is directed in the plane of the cantilever(s) cooperating with a current loop in/on the latter. Orienting the magnetic field along or perpendicular to the cantilever axis and controlling the current apprpriately allows for selective excitation of resonance or non-resonance modes and/or in a self-oscillation mode. The deflection of the cantilever is detected using piezoresistive or magnetic readout. The apparatus may be used as gas sensor, scanning force microscope, mechanical filter, temperature sensor or the like.Type: GrantFiled: October 1, 2001Date of Patent: December 30, 2003Assignee: Swiss Federal Institute of Technology ZurichInventors: Dirk Lange, Christoph Hagleitner, Oliver Brand
