Coupled mechanics in skin-interfaced electronics via computer vision methods

Recent advancements in materials and mechanics have paved the way for transforming rigid circuits into flexible electronics. Their ability to laminate onto the skin has led to the development of skin-interfaced electronics, including mechano-acoustic sensors and haptic systems. However, the challenges of the coupled mechanics between the skin and skin-interfaced electronics call for further understanding of biomechanics, bioelectronics, and their interactions. This perspective article highlights the emerging trend of employing computer vision methods to optimize the next generation of skin-interfaced electronics by characterizing associated biomechanics and vice versa. The cyclic research process involves the development of soft electronics, the identification of coupled mechanics, and their quantification using computer vision methods. The article describes state-of-the-art computer vision techniques in the context of skin-interfaced electronics and their potential applications in other forms of soft electronics.
