Inspired by nature, a new class of sensor, called a 'sensor with unique and unclonable characteristic', has been developed. Similar to sensors in nature, this one responds to a measurand and provides a unique output. Random variations in the sensor's structure are responsible for these unique characteristics. As random variations are difficult to measure, model and duplicate, it is impossible to clone the sensor. Such a sensor is very interesting, as it can be used as a hardware identifier, a sensor with an integrated identifier, and as a nature-like sensor.
Capacitive sensors with unique and unclonable characteristic are proposed. The sensors respond to tilt and provide unique and unclonable capacitance output. Random structural variations integrated into the sensor structure during the fabrication process are the sources of these unique and unclonable sensor characteristics. The design, modeling, simulation, optimization, fabrication, testing and applications of these capacitance-based, unique and unclonable tilt sensors are presented in this thesis.
