Abstract
In this contribution, we reply to comments made by Tkach et al. in our publication J. Materiomics 2023; 9:609. The main interest of our work is to synthesize a lead-free material, SrTi2O5 (STO), and then utilize it in the formation of composites and finally design the piezoelectric nanogenerator (PENG) for self-powered sensor applications. The authors have observed the presence of piezoelectric voltage and current output from the PENG. The authors humbly indicate that the PENG devices were poled using a DC poling setup as conditions mentioned in J. Materiomics 2023; 9:609 (Panda et al., 2023) [1]. The doping of STO into the PDMS increased from 2% to 20% (in mass). In this process, the piezoelectric output of the PENG device was observed to be highest for 15% (in mass) STO-PDMS composite. Besides, we agree with the comment raised by Tkach et al., and further we have addressed the issues in a step-by-step response as follows.
