In this work, we approached the sintering and novel crystallisation of the biologicals with a cold sintering technique. Advanced characterisation techniques such as X ray diffractogram, X ray photoelectron spectroscopy (XPS) and scanning electron microscopy (SEM) were used to study sintered soya bean powder (biological electret) pellets. Further, the electrets were prepared by contact poling and the piezoelectric properties studied with the help of piezoresponse microscopy (PFM).
