Thesis type RESEARCH

Description The project, which currently involves several PhD and MS students, is aimed at finding the location of person and identifying the person among a small set, using a synergy between new capacitance-based sensors and traditional ones (e.g. infrared).
Previous research by our group has developed pilot nodes, based on an RC oscillator, that measure capacitance via frequency, transmit it to a PC, and use the data to locate the person with an error of about 30cm in a 3mx3m room.
Possible thesis topics, spanning analogue and digital electronics, embedded systems and machine learning:
- capacitance measuring techniques highly resilient to noise (e.g., filtering, balanced sensor structures, shielding of measurement field).
- analogue and digital front-end circuitry, aimed at measuring very small capacitance in the presence of noise from the environment.
- sensor power management, especially controlling sleep time of various components (analogue, digital, radio).
- low-power implementation on node of some processing functions (filters, some machine learning algorithms).
- machine learning algorithms on the base station, to fuse data from different capacitive and other kinds of sensors.
