James Edward Zimmerman

Electrical engineer

1923-1999


James Edward Zimmerman was a North-American electrical engineer who invented and developed the SQUIDs, the superconducting quantum interference device.

In 1965, he realized that quantum interference could be observed in a superconducting loop with a single junction if it was excited by a radio-frequency bias. The single junction was an immediate success, yielding a fully practical magnetometer with exquisite sensitivity, limited only by the uncertainty principle.

The scientists of ByAxon got inspired by the SQUID detectors in their way towards sensing the activity of spinal cord neural cells, surpassing the requirements of the cryogenic temperatures that are required in SQUID detectors.
