Abstract
An method of torque measurement based on surface acoustic wave(SAW) technology is discribed.The principle is analyzed
the mathematical expression between the torture and the syntonic frequency is deduced
and the feasibility is tested.Using the RF signals to excite the SAW sensor
the torture can be calculated by analyzing the echo signals.
