“…This is a result of the dominance of applied forces from the surrounding medium over internal forces of the fiber such as those associated with bending and inertia at these small diameters. This study was inspired by numerous examples of acoustic flow sensing by animals (12)(13)(14)(15)(16). Our results indicate that this biomimetic device responds to subtle air motion over a broader range of frequencies than has been observed in natural flow sensors.…”

“…However, their applicability in a small space is often limited by their large size, high power consumption, limited bandwidth, high interaction with medium flow, and/or complex setups. There are many examples of sensory hairs in nature that sense fluctuating flow by deflecting in a direction perpendicular to their long axis due to forces applied by the surrounding medium (11)(12)(13)(14)(15)(16). The simple, efficient, and tiny natural hair-based flow sensors provide an inspiration to address these difficulties.…”

The ultimate aim of flow sensing is to represent the perturbations of the medium perfectly. Hundreds of millions of years of evolution resulted in hair-based flow sensors in terrestrial arthropods that stand out among the most sensitive biological sensors known, even better than photoreceptors which can detect a single photon (10 −18 -10 −19 J) of visible light. These tiny sensory hairs can move with a velocity close to that of the surrounding air at frequencies near their mechanical resonance, despite the low viscosity and low density of air. No man-made technology to date demonstrates comparable efficiency. Here we show that nanodimensional spider silk captures fluctuating airflow with maximum physical efficiency (V silk /V air ∼ 1) from 1 Hz to 50 kHz, providing an effective means for miniaturized flow sensing. Our mathematical model shows excellent agreement with experimental results for silk with various diameters: 500 nm, 1.6 μm, and 3 μm. When a fiber is sufficiently thin, it can move with the medium flow perfectly due to the domination of forces applied to it by the medium over those associated with its mechanical properties. These results suggest that the aerodynamic property of silk can provide an airborne acoustic signal to a spider directly, in addition to the wellknown substrate-borne information. By modifying a spider silk to be conductive and transducing its motion using electromagnetic induction, we demonstrate a miniature, directional, broadband, passive, low-cost approach to detect airflow with full fidelity over a frequency bandwidth that easily spans the full range of human hearing, as well as that of many other mammals.spider silk | airborne motion | flow sensing | acoustics | nanodimensional fiber M iniaturized flow sensing with high spatial and temporal resolution is crucial for numerous applications, such as high-resolution flow mapping (1), controlled microfluidic systems (2), unmanned microaerial vehicles (3-5), boundary-layer flow measurement (6), low-frequency sound-source localization (7), and directional hearing aids (8). It has important socioeconomic impacts involved with defense and civilian tasks, biomedical and healthcare, energy saving and noise reduction of aircraft, natural and man-made hazard monitoring and warning, etc (1-10). Traditional flow-sensing approaches such as laser Doppler velocimetry, particle image velocimetry, and hot-wire anemometry have demonstrated significant success in certain applications. However, their applicability in a small space is often limited by their large size, high power consumption, limited bandwidth, high interaction with medium flow, and/or complex setups. There are many examples of sensory hairs in nature that sense fluctuating flow by deflecting in a direction perpendicular to their long axis due to forces applied by the surrounding medium (11-16).

“…Near-field receptors are exquisitely sensitive, with deflections as small as 1 Å triggering neural responses (Shimozawa and Kanou, 1984;Humphrey and Barth, 2008). These receptors are generally tuned to low frequencies (<500 Hz) (Wang et al, 2000;Shamble et al, 2016). The tuning of each receptor depends primarily on its length, diameter and mass (Barth et al, 1993).…”

Anthropogenic noise and the bioacoustics of terrestrial invertebrates

Anthropogenic noise is an important issue of environmental concern owing to its wide-ranging effects on the physiology, behavior and ecology of animals. To date, research has focused on the impacts of far-field airborne noise (i.e. pressure waves) on vertebrates, with few exceptions. However, invertebrates and the other acoustic modalities they rely on, primarily near-field airborne and substrate-borne sound (i.e. particle motion and vibrations, respectively) have received little attention. Here, we review the literature on the impacts of different types of anthropogenic noise (airborne far-field, airborne near-field, substrate-borne) on terrestrial invertebrates. Using literature on invertebrate bioacoustics, we propose a framework for understanding the potential impact of anthropogenic noise on invertebrates and outline predictions of possible constraints and adaptations for invertebrates in responding to anthropogenic noise. We argue that understanding the impacts of anthropogenic noise requires us to consider multiple modalities of sound and to cultivate a broader understanding of invertebrate bioacoustics.
