Shape-changing polymers have emerged as promising materials for neural interface applications. Additionally, Qualia Oto’s polymers have a demonstrated biocompatibility as well as unique softening characteristics, allowing them to remain stiff at room temperature and then becoming compliant upon exposure to physiological temperatures and moisture. The initial stiffness is necessary for reliable handling and surgical implantation, whereas the softening post-implantation minimizes potential tissue scarring and trauma. 

In this video, exposure to a higher temperature (i.e., within the ear vs. room temperature) triggers the softening property of our material leading to curling of the originally-straight element; this then leads to gradual curling of the entire electrode array toward the modiolar wall of the scala tympani, in essence hugging the modiolus, significantly reducing risk of trauma and increasing the cochlear implant's efficacy.
