Abstract
The pressure transducer for measuring the clothing pressure is desired to be small in size and sensitive to the low pressure. Two types of the pressure transducer, disc type and balloon type, were used to measure the clothing pressure on human upper arm and three different models, that is, rigid body (model A), elastic body (model B), and rigid body covered with elastic stuff (model C).
The results were as follows :
1. In the measurement by the disc type transducer, the pressure higher than actually applied was detected on the model A, and the lower pressure on the models B and C and on the human upper arm.
2. The pressure measured by the balloon type transducer on the model A was approximately the same as the pressure actually applied. The lower pressure was determined on the models B and C and on the human upper arm, but the fall from the actual pressure was much smaller than that obtained by the disc type transducer.
From these experiments it could be said that the balloon type pressure transducer is more suitable than the disc type one to measure the clothing pressure on human bodies.
