Abstract

THE generation of electrical potentials by bone subjected to mechanical stress has been recently reported by two groups of investigators1,2. Bassett and Becker suggested a semiconduction mechanism as being the source of the phenomenon, while Shamos et al. favoured a classical piezo-electric mechanism similar to that earlier described by Fukada and Yasuda3. The semiconduction theory has recently been reported on in more detail4 and evidence presented for the formation of multiple pn junctions from the apatite crystal (p type) collagen fibre (n type) in the bone matrix. Similar inorganic pn junctions have been shown to be exceedingly stress sensitive5,6.
