Reviewer 2 Report
The article fits the journal and it is written quite well.
Some corrections:
a) Add a statistical analysis section
b) Lack of important references, such as:

Reviewer 3 Report
In this work, in order to solve the current problems, elastic and highly transparent polyurethane (PU) was first synthesized as the strain substrate following by the coating of sliver nanowires (AgNWs), which provided the strain-electric signal conversion path. The results of this manuscript are interesting and it can be accepted after following revisions.
1- English of the manuscript needs polishing.
2- The depth of technical discussions needs to go much further.
3- The literature review is required to be enriched by citing and commenting on the below articles focusing on strain sensing performance of nanocomposites: [Composites: Part A 163 (2022) 107244]; [Acta Materialia 230 (2022) 117870].
4- The percentage of nanopartcile in each experiment should be clearly stated.
5- Is it possible to study the effect of nanoparticle percentage on the stress-strain curves of recycled AgNWs/PU?
6- A brief discussion about important parameters affecting the stress-strain curves of AgNWs/PU should be added to the introduction. One of the main factors affecting the nanocomposite behavior is agglomeration of nanoparticles as mentioned in the following reference: [International Journal of Engineering Science 157 (2020) 103392].
7- What are the limitations of your experiments and research data?
English of the manuscript needs polishing.
