The measurement of tension in strings and soft tissues is of critical importance in many applications, including orthopedic surgeries. Various sensors have previously been designed for the measurement of tension, but they all require either attachment of the sensor to the string or the use of an external-inertial reference. This paper presents two new sensors to estimate tension in strings without...
This paper presents a novel method to read a passive capacitive sensor in telemetry by using inductive coupling. While classical inductive coupling approaches measure sensor capacitance by identifying the resonant frequency of the sensor with a sweep of radio frequency (RF) signals, the proposed method estimates the capacitance change in real-time by algebraically manipulating two measurements (the...
