Publication number: 20250041866Abstract: A sensor for detecting a target analyte in a sample includes a pair of conducting electrodes that are separated by a gap. An insulator is disposed in the gap between the electrodes. Plural wells are defined by one of the electrodes and the insulator, to expose the other of the electrodes. The wells are configured to receive a sample including a target analyte. The target analyte, when present in the sample received in the wells, modulates an impedance between the electrodes. The modulated impedance, which is measurable with an applied electrical voltage, is indicative of the concentration of the target analyte in the sample. The wells can include antibodies immobilized inside the wells, to bind the target analyte, which can be a cytokine. Also provided are a method for label-free sensing of a target analyte in a sample, and a transcutaneous impedance sensor for label-free, in-situ biomarker detection.Type: ApplicationFiled: August 21, 2024Publication date: February 6, 2025Inventors: Pengfei Xie, Mehdi Javanmard, Mark George Allen, Wen Shen, Naixin Song

Publication number: 20230316038Abstract: Artificial material systems that seek to mimic the basic processes of life must perform multiple complex functions including responsiveness, motion, and metabolism. Networks of programmable materials offer a pathway toward achieving these functions by altering local chemical, physical, and structural properties to enable control. We demonstrate the ability to perform multiple complex functions in a single soft elastomeric material system by reconfiguring, in situ, passive bistable fluidic diodes that are inspired by mammalian venous valves. We show how pneumo-mechanical programmability allows these silicone elastomer diode assemblies to accomplish, without rearranging the fluidic circuit, multiple functions including pumping (motion), energy storage/discharge (metabolism), logic operations (response), and signal filtering/rectification.Type: ApplicationFiled: March 31, 2023Publication date: October 5, 2023Applicant: BOARD OF REGENTS, THE UNIVERSITY OF TEXAS SYSTEMInventors: Wen SONG, Thomas C.

Patent number: 11720173Abstract: Aspects of the present disclosure are directed to a multi-sensor don/doff detection system for an artificial reality device headset. The multi-sensor don/doff detection system can use a combination of a proximity sensor, an inertial measurement unit (IMU), and an eye tracking/face tracking (ET/FT) unit to make these determinations. However, when both the ET/FT system and proximity sensor system are active, they can have system coexistence issues. Thus, only one of these systems can be used simultaneously. The multi-sensor don/doff detection system can more accurately identify don events by using input from the proximity sensor and the IMU. The multi-sensor don/doff detection system can also more accurately identify doff events by using input from the IMU and either A) the proximity sensor when the ET/FT system is disabled or B) the ET/FT system when the ET/FT system is enabled.Type: GrantFiled: December 15, 2022Date of Patent: August 8, 2023Assignee: Meta Platforms Technologies, LLCInventors: Dong Yang, Qiang Zhang, Wen Song, Theresa Loney Casarez

Patent number: 11553656Abstract: A gardening apparatus includes one or more of a base, a fluid reservoir, and a plant tray or support disposed on the reservoir. The support is adapted for receiving one or more modular plant inserts, and can define a flow structure for channeling fluid to each insert. A pump supplies fluid from the reservoir to the plant tray or support, with a light assembly adapted to generate a spectrum of light for growth of plants from the inserts. A processor is configured for controlling fluid flow from the pump, the light spectrum generated by the lighting elements, or both. For example, the processor can use a dynamic recipe, algorithm or control schedule to modulate the fluid flow or spectrum based the plant type, growth stage, height, plant health data, digital phenotyping data, or ambient conditions, or a combination thereof.Type: GrantFiled: April 27, 2020Date of Patent: January 17, 2023Assignee: AVA Technologies Inc.Inventors: Yo Wen Song, Chase Arihiro Ando, Michael Reza Nasseri, Darshil Panagar, Chiragh Dewan
