1. THE METHOD OF DETERMINING THE CHANGE IN STRESS IN A PARTICULAR DIRECTION IN A BLOCK OF MATTER WHICH IS ADAPTED TO UNDERGO A KNOWN CHANGE IN DIMENSION THE SAID DIRECTION IN THE STRESS RANGE TO BE DETERMINED THE STEPS COMPRISING:
- EMBEDDING AN ELEMENT HAVING PIEZORESISTIVE CHARACTERISTICS WHICH IS A SENSITIVE AXIS IN A PROTECTIVE RIGID HOUSING WHICH IS ADAPTED TO UNDERGO A SMALLER CHANGE IN DIMENSION THAN SAID BLOCK OF MATTER IN THE STRESS RANGE TO BE DETERMINED TO PROTECT THE ELEMENT THEREIN;
CONNECTING A PAIR OF OUTPUT LEADS TO ENDS OF THE SAID ELEMENT THROUGH WHICH TO SENSE CHANGE IN RESISTIVITY OF THE ELEMENT AS A FUNCTION OF CHANGES IN STRESS ALONG SAID SENSITIVE AXIS;
AND EMBEDDING THE HOUSING IN SAID BLOCK OF MATTER WITH THE STRESS SENSITIVE AXIS OF THE ELEMENT SUBSTANTIALLY COINCIDENT WITH SAID PARTICULAR DIRECTION IN WHICH THE STRESS IS TO BE MEASURED, WITH THE PAIR OF OUTPUT LEADS EXTENDING FROM SAID BLOCK, WHEREBY THE CHANGE OF STRESS IN SAID PARTICULAR AXIS IS DETERMINED AS A FUNCTION OF A CHANGE IN THE RESISTIVITY ACROSS SAID PAIR OF OUTPUT LEADS.
