Lab-synthesized PEDOT:PSS with high conductivity that keeps working under large strain, plus elastomer surface engineering so the films stay attached when stretched.
Soft, skin-mimicking hydrogels from gelatin, alginate, PVA and cellulose whose resistance follows strain without lag, for reliable sensing and hydrovoltaic power.
Skin-attachable strain and pressure sensors read out wirelessly, with machine learning that classifies body motion and gesture patterns from the sensor signals.
