Self-Sensing Concrete Assistant

An integrated intelligence suite for the Inframat-X Lab. Use the Predictor to estimate piezoresistive stress sensitivity based on 224 experimental records, or consult the Research Assistant to synthesize findings from our 130-paper technical corpus. All synthesized answers include bidirectional citations (e.g., [18], [71]) mapped directly to the laboratory’s verified source index.
