His research areas include piezoelectricity of biological and synthetic polymers, electrical stimulation of bone growth, and biorheology of blood and its clotting. Fukada discovered piezoelectricity in bone and initiated a field of research that is active to this day.
He also found piezoelectricity in innumerable other biological materials including DNA. Fukada describes his childhood, his undergraduate research at the University of Tokyo in the final days of World War II, the founding of the Kobayasi Institute of Physical Research, and his early research on the elastic properties and piezoelectricity of wood. Iwao Yasuda and their discovery of piezoelectricity in bone in 1957 and its long-term importance. He described leaving the Kobayasi Institute and his move to Riken where he carried out research on rheology, hemorheology, and biorheology.
Die piezoelektrische Polarisation bei Holz kann für die Lösung technischer Probleme, wie z. bei der Messung der Schallgeschwindigkeit in Holz praktisch eingesetzt werden.
Die physiologische Bedeutung des piezoelektrischen Effekts in lebenden Pflanzen ist bisher noch unbekannt.
Eiichi Fukada was born on 28 March 1922 in Kokura, Japan. He received several awards from academic societies in Japan, the Galvani Award from the International Symposium on Electrobiology in 1989 and the Poiseille Gold Medal Award from the International Society of Biorheology in 1995.
He has published about 250 papers in English and about 200 papers in Japanese.
He was a research member at the Kobayasi Institute of Physical Research (KIPR), Tokyo from 1944 to 1963; British Council Scholar at the Department of Physics, Imperial College of Science and Technology, London from 1956 to 1958; Chief Research Member of the Biopolymer Physics Laboratory, the Institute of Physical and Chemical Research (RIKEN), Tokyo from 1963 to 1980; Executive Director of RIKEN from 1980 to 1984; Research Advisor at the Institute for Super Materials, ULVAC, Tsukuba from 1987 to 1998; and a member of the Board of Directors at KIPR from 1992 to 2002. He was Visiting Professor at Gakushuin University, Tokyo in 1961-1980, New York University in 1965-1966, University of San Paulo in 1974, Technical University of Darmstadt and University of Constance in 1986.
degree in 1960, both from the Department of Physics, University of Tokyo.
The specimens were cut out from the femur of man and ox, and dried completely by heating.The specimens which were boiled in hot water and afterwards dried completely showed little change in the piezoelectric effect, the fact ascertaining that the effect is not of biological origin.The origin to piezoelectricity in bone may be ascribed to the piezoelectric effect of the crystalline micelle of collagen molecules.This manuscript is being made available for research purposes only.All literary rights in the manuscript, including the right to publish, are reserved to the IEEE History Center.
