summary

A digitally knitted capacitive fabric uses one conductive carbon-coated yarn with only two external connections to create a 36-button sensor and several form factors like a piano keyboard and volume pad. Real-time acquisition uses swept-frequency Bode analysis over 96 frequencies producing 250 temporally related measurements per touch, reduced to statistics and a baseline subtraction. A three-layer LSTM model trained with 386 samples per class yields 66% subject-independent accuracy (chance ≈3%), with EMI robustness at 80% and stretch robustness at 37%.
