Bio-inspired organic electrosense transistor for impalpable perception

Artificial sense technologies predominantly rely on visual and tactile
input, which often prove inadequate in obscured or opaque environments.
Inspired by the natural electrosensory capabilities of electrogenic
fishes, we introduce an organic electrosense transistor designed to detect
electric fields generated by nearby objects, facilitating the creation of
impalpable perception systems. Unlike traditional sensors, our
electrosense transistor perceives bipolar electric fields with high
sensitivity and stability. We employ compact models and device simulations
to elucidate the mechanisms of charge induction and transport within
organic electrosense transistors when exposed to spatial electric fields.
Demonstrating its practical utility, we show that robots equipped with our
electrosense transistor can successfully navigate and detect concealed
objects without requiring direct contact. This work not only advances the
understanding of charge dynamics in electrosensory systems but also
establishes a platform for developing highly sensitive, non-invasive
artificial sensing technologies applicable in surveillance,
search-and-rescue, and other challenging environments.
