Sensory System for Unconventional Electronics

Lead Research Organisation: University of Surrey
Department Name: ATI Electronics

Abstract

The project focuses on the materialization of a bio-inspired tactile-Short Term Memory (t-STM) low power device, which exploits the electrical properties of sol-gel amorphous Titania (a-TiO2) - based Resistive Random Access Memory (ReRAM). The ultimate target is the fabrication of the active and sensory cells by using low cost materials and processes. A solely additive approach, the inkjet printing process, is chosen as the main fabrication technique. The tactile sense, being the most essential modality that affects our cognition and interaction with our surroundings, then its integration into a bio-inspired processing element could contribute to the realization of a sensory building block for an artificial intelligent system. The potential application of the present project is in soft robotics.

Description The solution - ink that developed meets the properties for inkjet-printed memristive devices, which was a vital part of the present project. Additionally, the final fully printed devices show biomimetic properties when electrically characterised. Both findings are quite promising for a future alternative of printed and flexible electronic devices for robotic and biomimetic applications.
Exploitation Route The present work has a strong research interest, as the switching mechanism of memristive devices in general is still under investigation, and the printed devices are currenlty in an infant stage. Additionally, a full report of solutions-inks that are compatible with the inkjet printing technology, and especially for memristive devices are scarce if not absent. This makes the current project a promising path for a future commercialization.
