A flexible spiking hair sensillum for ultralow power density noncontact perception.

ABSTRACT: The ability to recognize targets before physical contact is crucial for organisms' adaptability to real-world environments. However, current noncontact sensing systems face challenges in power density and biological fidelity. Here, we report a flexible spiking hair sensillum (FISH) with an ultralow power density < 100 nanowatts per square millimeter for achieving noncontact tactile perception (NCTP). This device can transduce proximity or airflow into spike trains with a frequency range of ~500 to 1500 hertz. A spiking NCTP system is developed, achieving high accuracy (>92%) in multidimensional recognition of noncontact targets, mediated by airflow. Furthermore, we show that a spider robot equipped with a FISH matrix outperforms one relying exclusively on machine vision in tasks of predati
