Abstract: Electronic device characterization platforms, systems, devices, and methods for use in testing instruments, devices, and sensors that is portable, modular, multiplexed, and automated are disclosed. The system includes a substrate, a chip adapter, such as a chip socket, and an optional housing. Chip samples to be tested can be disposed in the chip adapter and various environmental modules designed to supply different environmental conditions to the chip sample can be disposed over the chip adapter, enabling testing of the chip samples to be performed in the different environment conditions. The system can further include various connectors that allow for add-on modules to be included as part of the system. Methods of characterizing electronic devices and sensors are also disclosed.

Abstract: A fully-printed sensor chip for measuring prothrombin time of a blood sample. The sensor chip includes a pair of electrodes and a pair of contact pads, each electrically coupled to a different one of the electrodes, printed on the surface of the substrate using conductive ink materials. When a blood sample is placed on the sample chip in contact with both electrodes, an impedance of the blood sample is determined based on a measured impedance between the two contact pads. As the blood sample clots, the impedance value changes and the prothrombin time for the blood sample is determined based on a measurement time of a maximum impedance value. A resistive bridge printed on the substrate surface between the contact pads increases a baseline measurement for the sensor chip to a value within a range that is measurable by lower-cost measurement equipment.
