The study presented here relates a tissue hardness (stiffness) measurement system, or more precisely for example, external labor transducer for monitoring of gravidae, including possible cases of fetal and maternal combined signal transducer. As a theory of measurement, suction cup is applied on subject body surface where the tissue hardness thereon or shallow depth, is to be measured. Unlike conventional “pushing” type measurement, our method is to apply negative pressure (sucking) thereon by suction cup. Response of the body surface Read More …
