   Robust Readout Method for Cross-Point Resistive Arrays Based on Time-Domain Optimization

   To address the inaccuracy of conventional frequency-domain readout caused by long interconnects and environmental noise in robotic tactile sensing, this study proposes a time-domain optimization readout method that determines resistance values by fitting a time-domain observation model and using the full waveform rather than only spectral amplitudes. In simulations of a 16×16 array, the method reduced the mean readout error by 20% compared with the baseline; validation over 1,000 trials showed reductions of 24.6% in mean error and 77.6% in standard deviation, and the improvement was also confirmed in cross-point array simulations emulating tactile sensor resistance distributions.

The trend compares participants observed throughout the same period, so its range may be smaller than the current interest count. Move or tap to inspect each hour; use the arrow keys on a keyboard.
