Advancements in smart soft materials are enhancing the capabilities of robotic manipulators in object interactions and complex tasks. Mechanochromic materials, acting as lightweight sensors, offer easily interpretable visual feedback for localized stress detection, structural health monitoring, and energy-efficient robotic skins. Herein, an innovative mechanochromic soft end-effector capable of discerning local contact stresses during mechanical interactions with objects is presented and their relative position is ascertained.

Introduction

The Extreme Mechanics Letters (EML) Young Investigator Award (YIA) 2024 edition is organized by the journal and Elsevier to honor the best paper by a young scientist. The papers must have been published in volumes 63-69, from 2023 to 2024.

The award is made annually to the corresponding authors of the paper who received their Ph.D. no more than 10 years prior to the year of award. Corresponding authors who have yet to receive a Ph.D. will also be considered and self-nominations are allowed. 

The contact between a rigid Hertzian indenter and an adhesive broad-band viscoelastic substrate is considered. The material behavior is described by a modified power law model, which is characterized by only four parameters, the glassy and rubbery elastic moduli, a characteristic exponent n and a timescale tau0.
