title: Improvement of the magnetneumometer.
abstract: We have improved the magnetneumometer in order to extend the measurement range and to make small-sized transmitting and receiving coils, for the purpose of applying it to measure the breathing rib cage and abdomen displacement. As a result, the measurement range is 10-80 cm, the noise level is less than 0.02 mm, and small and light coils (30 x 16 x 3 mm, 4 g) have been incorporated.
