LoC sensor array platform for real-time coagulation measurements
(IEEE, 2014)
This paper reports a MEMS-based sensor array enabling multiple clot-time tests in one disposable microfluidic cartridge using plasma. The versatile LoC (Lab-on-Chip) platform technology is demonstrated here for real-time ...
MEMS based blood plasma viscosity sensor without electrical connections
(IEEE, 2013)
A MEMS based viscometer is reported. The device has a disposable cartridge and a reader. The cartridge contains microfluidic channels and a MEMS cantilever sensor. The reader contains the actuator and the readout optics ...
Cantilever array oscillators with nonlinear optical readout
(IEEE, 2015)
MEMS array oscillators typically require a separate detector and feedback loop for each oscillator. We show that grating-based-optical-readout induces nonlinearity, which enables simultaneous operation of an array-of-oscillators ...
Blood coagulation time measurement using a 1μL of whole blood on a TE mode BAW resonator
(IEEE, 2018-12-20)
This paper presents a possible way to blood coagulation time measurement using a TE (Thickness Extensions) mode BAW (Bulk Acoustic Wave) resonator which requires as low as 1 micro-liter of whole blood. The blood sample is ...
Precision density and viscosity measurement using two cantilevers with different widths
(Elsevier, 2015)
We introduce a novel method for fast measurement of liquid viscosity and density using two cantilevers with different geometries. Our method can be used for real-time monitoring in lab on chip systems and offer high accuracy ...
Microcantilever based LoC system for coagulation measurements
(Chemical and Biological Microsystems Society, 2014)
In this paper, a microcantilever-based system enabling multiple coagulation tests on the same disposable cartridge is demonstrated. The system consists of independent cartridge and reader unit. The actuation of the nickel ...
Mutual radiation impedance of circular CMUTs on a cylinder
(IEEE, 2016)
In ultrasound imaging, cross coupling of transducer elements through the medium has significant effect on the frequency response, thus affecting the quality of the ultrasound image. In Side-Looking Intravascular Ultrasound ...
Design of a quad element patch antenna at 5.8 GHz
(IEEE, 2018)
This paper presents simulation and experimental verification of a quad microstrip patch antenna that operates at 5.8 GHz. Sonnet antenna design software was used to simulate the performance of the antenna. To reduce the ...
Coagulation measurement from whole blood using vibrating optical fiber in a disposable cartridge
(SPIE, 2017-11)
In clinics, blood coagulation time measurements are performed using mechanical measurements with blood plasma. Such measurements are challenging to do in a lab-on-a-chip (LoC) system using a small volume of whole blood. ...
Equivalent circuit for capacitive micromachined ultrasonic transducers to predict anti-resonances
(Springer Nature, 2020-12)
Equivalent circuit models have been long used to evaluate the dynamics of the capacitive micromachined ultrasonic transducer (CMUT). An important parameter in the characterization of a CMUT is the anti-resonance frequency, ...
