In this talk, we explore the significance of ion dynamics in solid-state gel electronics for neuromorphic E-SKIN applications such as tactile perception, biochemical and electrophysiological sensing, neural interfaces, and therapeutic treatments. We conclude with future perspectives and challenges in gel-based electronic devices, highlighting the need for ongoing innovation in iontronic materials to further enhance the integration of these technologies in the versatile fields. Additionally, we aim to extend our discussion to the emulation of biological perception via artificial synapses, concluding with future perspectives and challenges in neuromorphic system development.
