Biodegradable polymers are attracting attention as materials with low environmental impact. Cellulose with chirality is known to develop piezoelectricity by orientation. The piezoelectric properties of cellulose have been reported by direct measurements, but there have been few reports on piezoelectric resonance measurement, which can more rigorously determine the piezoelectric properties of cellulose. In this study, we focused on cellulose diacetate film, a biodegradable polymer, and evaluated its piezoelectric properties by the piezoelectric resonance measurement.
