1.	________________ material employed for making diaphragm to measure pressure.(a) zirconate titanate(b) barium titanate(c) tourmaline(d) phosphor bronzeThis question was posed to me in an online quiz.Asked question is from Implantable Telemetry Systems in chapter Biomedical Telemetry of Biomedical Instrumentation
Answer» Correct choice is (d) PHOSPHOR BRONZE To EXPLAIN: The motion of the diaphragm is measured in terms of electric signals. Tourmaline, barium titanate and zirconate titanate are piezo electric materials.Phosphor bronze is used to MAKE diaphragm to measure PRESSURE.
