This course provides the basic skill and technique to conduct a biomechanical experiments. This course will cover the application of electronics, the principle of strain gage, and the selection of transducers. The application of electronics illustrates the application of operation amplify and transistor on the amplifying and filtering of voltage. How to use a strain gage as a force or displacement sensor will also be taught. In addion, students will lean how to read the technique note of transducers and how to choose the for their experiments. The technique of analysing the data will also be illustrated during the class.
