β¦ Synopsis
This paper investigated piezoelectricity of the gelatin gel. Polarized infrared and thermal stimulated current experiments provided the proof of the origin of the piezoelectricityoriented dipoles. Effects of crosslinking, ionic strength, and stress on piezoelectricity were discussed as well. We found that the voltage decreased as the crosslinking time increased, had a minimum value of ionic strength, and increased with the stress, respectively.

## Abstract The solβgel transition of gelatin, measured by thermal analysis and viscosity measurement, was analyzed in terms of the change in hydration state of polymer molecules. A new thermodynamic model was proposed in which the effect of water potential is explicitly taken into account for the
