Ear-Bot: Locust Ear-on-a-Chip Bio-Hybrid Platform

Sensors (Basel). 2021 Jan 1;21(1):228. doi: 10.3390/s21010228.


During hundreds of millions of years of evolution, insects have evolved some of the most efficient and robust sensing organs, often far more sensitive than their man-made equivalents. In this study, we demonstrate a hybrid bio-technological approach, integrating a locust tympanic ear with a robotic platform. Using an Ear-on-a-Chip method, we manage to create a long-lasting miniature sensory device that operates as part of a bio-hybrid robot. The neural signals recorded from the ear in response to sound pulses, are processed and used to control the robot's motion. This work is a proof of concept, demonstrating the use of biological ears for robotic sensing and control.

Keywords: acoustic response; bio-hybrid; bio-robot; ear-on-a-chip; locust robot.
