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 ...
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 ...
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. ...
A prism-based non-linear optical readout method for MEMS cantilever arrays
(Elsevier, 2016-10-15)
This paper demonstrates the use of a single right-angle prism for the optical readout of micro-electro-mechanical systems (MEMS) cantilever arrays. The non-linear reflectivity arisen from the internal reflection at the ...
Two cantilever based sytem for viscosity and density monitoring
(IEEE, 2015)
Viscosity and density measurements in liquids in real-time is challenging. Previous MEMS based approaches use frequency sweeps for the purpose and those methods are slow and not real-time. We show that high precision ...
Disposable cartridge biosensor platform for portable diagnostics
(SPIE , 2017)
We developed two types of cantilever-based biosensors for portable diagnostics applications. One sensor is based on MEMS cantilever chip mounted in a microfluidic channel and the other sensor is based on a movable optical ...
Optical fiber array based simultaneous parallel monitoring of resonant cantilever sensors in liquid
(Elsevier, 2016-05-01)
This paper reports a novel method for simultaneous resonance monitoring of MEMS cantilevers using phase based dynamic measurements without any electrical connections to the sensor array. MEMS cantilevers are made of ...
