Investigations on the existence of piezoelectric property of a bio-polymer – chitosan and its application in vibration sensors

Abstract

A variety of physical and chemical properties of bio-polymers like chitosan have been investigated although their inherent behavior, such as piezoelectricity, has not been investigated to date.

Nanocellulose and chitosan based films as low cost, green piezoelectric materials

“…Correspondingly, the piezoelectricity of chitin has been reported in the 1970s (Fukada & Sasaki, 1975), but literature concerning the piezoelectric sensitivity of chitosan is scarce. Piezoelectric sensitivity values of chitosan have been reported in our preliminary study (Hänninen, Rajala, Salpavaara, Kellomäki, & Tuukkanen, 2016) as well as in a recent study where the usage of chitosan in piezoelectric vibration sensors was reported (Praveen, Murugan, & Jayakumar, 2017).…”

Recent Developments and Prospects of M13- Bacteriophage Based Piezoelectric Energy Harvesting Devices

“…Recently, there has been a growing interest in the biopiezoelectric materials to overcome these limitations. Polysaccharide materials [24][25][26][27], viruses [28][29][30][31], and self-assembled biomaterials [32,33] have been identified as good candidates, because their piezoelectric constants are higher than those of previous natural biomaterials, and they are possible to mass-produce. Especially, it has been found their physical and chemical properties can be modulated by their morphology, surface charges, and phases, and the piezoelectric response is directly related to these.…”

“…They combined the knowledge of pyroelectricity with their understanding of crystal structures and behavior, and demonstrated the first piezoelectric effect by using crystals of quartz and Rochelle salt. Since then, many researchers have discovered and reported the piezoelectric properties of organic [15,16], inorganic [7][8][9][10][11][12][13][14]17], and biomaterials [18][19][20][21][22][23][24][25][26][27][28][29][30][31][32][33].…”
