Abstract
Nowadays, portable and wearable electronic devices are now an important role in the daily lives of people nowadays. Especially, in the field of biomedical devices. These devices required a highly efficient external power source and have to be able operated in contact with
the human body. Therefore, in this work, the authors pay attention to develop triboelectric
nanogenerators (TENGs) that can harvest the mechanical energy and converting it into electricity
by contacting of two materials and induced the electricity for serving as the electrical supply.
Using bacterial cellulose (BC) and chitosan (CS) natural polymer as the main faction materials,
then improving output efficiency of the composite films with bio-piezoelectric material from
gamma-glycine ( g-gly) amino acid in different ratios to study the amount of g-gly that affects
physical appearance, morphology, and the electrical output. The results showed the composite
films remain its translucency and flexibility despite the increased of g-gly content. When
examining the morphology of the composite films, it was found that the g- gly particles
dispersed in the matrix increased by the amount of g-gly. Then, the electrical output is
investigated. It was found that g-gly was able to increase the electrical output value of natural
polymer. In the BC matrix, with 5 wt% g-gly added, the output voltage (Voc), current (Isc) and
power can went up to ~46 V and ~19.3 nA and ~725.22 mW respectively. In the CS matrix, 50
wt% added, can provide output voltage (Voc), current (Isc) and power of ~78.81 V ~64 nA and
~705.96 μW, respectively. Furthermore, both types of composite films can charge capacitors at
two different capacities of 0.22 μF and 0.33 μF. This research indicates that appropriate g-gly
content is an important factor in the preparation of quality composite films and good electrical
output. with this work. The authors expect that this study will provide a novel way to enhance
the biocompatible, green and eco- friendly energy harvesting devices from natural materials to
achieve high performance.
