I am looking into algorithms/techniques for feature extraction for accelerometer data - to then be used in classification.

FFT is incredibly popular, however would this work on accelerometer data? I've also seen PCA, but that isn't quite so popular.

Will PCA work as a possible feature extraction algorithm?
