This thesis describes the development of low Tc superconducting quantum interference devices (SQUIDs) based on the relaxation oscillation principle. SQUIDs are the most sensitive magnetic flux sensors available nowadays. As they can detect very accurately any physical quantity that can be converted to a magnetic flux, their field of applications is wide-ranging. Examples of applications are the detection of the tiny magnetic fields generated by the human brain, the measurement of voltages in the picovolt range and the readout of cryogenic particle detectors.
