This study investigates the mechanical behavior of silicone mixtures and their application in pneumatic soft actuators. A comprehensive experimental methodology was used to evaluate 15 silicone combinations, focusing on Young\u2019s modulus, fracture stress, and fracture strain. Through an ordinary least squares regression analysis of the resulting Young\u2019s Moduli, we identified key predictors and interactions that govern material properties, achieving an\n                    <jats:inline-formula>\n                      <jats:tex-math>\n                        \n                      <\/jats:tex-math>\n                      <mml:math xmlns:mml=\"http:\/\/www.w3.org\/1998\/Math\/MathML\" overflow=\"scroll\">\n                        <mml:mrow>\n                          <mml:msup>\n                            <mml:mi>R<\/mml:mi>\n                            <mml:mn>2<\/mml:mn>\n                          <\/mml:msup>\n                        <\/mml:mrow>\n                      <\/mml:math>\n                    <\/jats:inline-formula>\n                    value of 0.932 and an adjusted\n                    <jats:inline-formula>\n                      <jats:tex-math>\n                        \n                      <\/jats:tex-math>\n                      <mml:math xmlns:mml=\"http:\/\/www.w3.org\/1998\/Math\/MathML\" overflow=\"scroll\">\n                        <mml:mrow>\n                          <mml:msup>\n                            <mml:mi>R<\/mml:mi>\n                            <mml:mn>2<\/mml:mn>\n                          <\/mml:msup>\n                        <\/mml:mrow>\n                      <\/mml:math>\n                    <\/jats:inline-formula>\n                    of 0.762. Stress\u2013strain analyses revealed a broad range of achievable Young\u2019s Moduli (0.098\u20130.428 MPa), fracture stress (0.015\u20131.093 MPa), and fracture strains (0.984\u20135.145). To validate these findings, three pneumatic actuators were fabricated using silicone mixtures with varying strain-limiting layers. Their performance, evaluated by bending angle measurements under incremental air injection, showed significant differences, underscoring the importance of material selection in actuator design. Actuators with low modulus, high strain mixtures achieved greater bending angles, making them ideal for applications requiring high flexibility. These results establish a framework for systematically designing and optimizing silicone mixtures for soft actuators, offering insights into their mechanical behavior and practical implications in soft robotics. This work advances the field by providing a detailed understanding of material-property relationships and their role in achieving precise actuation in soft robotic systems.\n                  <\/jats:p>","DOI":"10.1088\/1748-3190\/ae6e83","type":"journal-article","created":{"date-parts":[[2026,5,15]],"date-time":"2026-05-15T22:52:53Z","timestamp":1778885573000},"page":"046002","update-policy":"https:\/\/doi.org\/10.1088\/crossmark-policy","source":"Crossref","is-referenced-by-count":0,"title":["Tailoring silicone mixtures for soft robotics: predictive modeling and experimental validation in pneumatic soft actuators"],"prefix":"10.1088","volume":"21","author":[{"ORCID":"https:\/\/orcid.org\/0009-0001-8449-9771","authenticated-orcid":true,"given":"Daniel","family":"Johnson","sequence":"first","affiliation":[{"name":"University of North Texas"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-3175-0587","authenticated-orcid":true,"given":"Trevor","family":"Exley","sequence":"additional","affiliation":[{"name":"University of North Texas"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Marc-Anthony","family":"Torres","sequence":"additional","affiliation":[{"name":"University of North Texas"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0009-0009-0081-1560","authenticated-orcid":true,"given":"Jack","family":"Slayton","sequence":"additional","affiliation":[{"name":"University of North Texas"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-0603-6683","authenticated-orcid":true,"given":"Melanie","family":"Ecker","sequence":"additional","affiliation":[{"name":"University of North Texas"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0009-0006-8295-0369","authenticated-orcid":true,"given":"Amir","family":"Jafari","sequence":"additional","affiliation":[{"name":"University of North Texas"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"266","published-online":{"date-parts":[[2026,6,12]]},"reference":[{"key":"bbae6e83bib1","doi-asserted-by":"publisher","DOI":"10.1002\/adma.202004413","type":"journal-article","article-title":"Becoming sustainable, the new frontier in soft robotics","volume":"33","author":"Hartmann","year":"2021","journal-title":"Adv.
