Abstract
Systems, devices, and methods for detecting cannabinoids in liquid or gaseous samples. In one aspect, the present invention uses a sensor element and two electrical circuit elements. When the sensor element is in contact with a sample containing cannabinoid, interactions between the sensor element and the cannabinoid changes or affects the sensor element's electrochemical properties. Using the two electrical circuit elements, this change can be detected. An analog signal relating to the changed electrochemical properties can be measured using the two electrical circuit elements. In one implementation, there is provided an organic field effect transistor (OFET) whose signal changes when in contact with a cannabinoid containing sample.
