Method of manufacturing a piezosensitive material or a magnetic material

摘要

A method is disclosed for producing magnetic or piezoelectric particles consisting of dried microorganisms which contain fixed magnetic or piezoelectric powder. The microorganisms are cultured in a nutrient medium containing the magnetic or piezoelectric powder which is then fixed or ingested by the microorganism. The microorganisms containing the magnetic or piezoelectric powder are then extracted from the nutrient medium and dehydrated to obtain dry particles. The dry particles may be compacted or inserted into a matrix to form a composite material.
