✦ Synopsis

An improved flat dc-thin film SQUID with Dayem bridges has been used for the measurement of the magnetic fields of human heart and skeletal muscles. Using an antenna in form of superconducting asymmetric second derivative gradiometer a sensitivity to magnetic fields of I x 10 -12 T Hz-1/2 could be reached. The main features of measurement and some results are presented.
