Fully printed prothrombin time sensor for point-of-care testing

CoaguChek point-of-care testing prothrombin time monitors.

A system for quality assessment (QA) of the CoaguChek (Roche Diagnostics, Mannheim, Germany) point-of-care testing prothrombin time monitor has been developed by the European Concerted Action on Anticoagulation. Hitherto there has not been an adequate rapid method for CoaguChek QA. Sets of 5 certified international normalized ratio (INR) plasma samples were tested on 539 CoaguChek monitors by e...

Point-of-care Testing for Oral Anticoagulant Management with Portable Prothrombin Time Systems

A National Field Study of Quality Assessment of CoaguChek Point-of-Care Testing Prothrombin Time Monitors

Fully inkjet printed SnO2 gas sensor on plastic substrate

A tin dioxide (SnO2) sensor was fabricated by inkjet printing onto polyimide foil. Gold electrodes and heater were printed on each side of the substrate. A SnO2 based ink was developed by sol-gel method and jetted onto the electrodes. A final annealing at 400°C compatible with the polymeric transducers allowed to synthetize the SnO2 sensing film. Electrical measurements were carried out to char...

Fully Distributed Multi-sensor Change-point Detection

Change-point detection has been a fundamental problem in quality control, hazards monitoring and cybersecurity. With the ever-growing complexity of system and enlarging number of sensors, multi-sensor detection algorithms are in real demand. However, most existing detection algorithms consider a centralized approach, meaning that one collects all data at one location, which sometimes may be inf...
