“…Distributed flow sensors have been used in flush air data systems in a number of high-performance aircraft, such as the X-33 [13] and the space shuttle [14], where traditional air data booms were impractical. However, these distributed airflow sensors are also increasingly being developed for small unmanned aerial vehicles (UAVs) [15] where there is a need for more agile flight control when flying in cluttered turbulent environments. These systems have used a number of different types of sensors such as diaphragm-based pressure sensors [16], hot film sensors [17], and artificial hair sensors [18].…”

“…For decades, MAV has received considerable critical attention and has synchronously developed in two fields, including microaircrafts based on bionic design and cyborg insects whose locomotion are controlled by artificial stimulation modules. Due to inheriting the senor organs and athletic ability of the insect carriers, cyborg insects remedy the technical limitations of bionic aircrafts in terms of deficient sensing equipment [6,7], poor adaptability in an unstructured environment [8], and difficulty in continuous power supply [9]. Moreover, cyborg insects have incomparable application potential in biodiversity protection.…”

The artificial locomotion control strategy is the fundamental technique to ensure the accomplishment of the preset assignments for cyborg insects. The existing research has recognized that the electrical stimulation applied to the optic lobes was an appropriate flight control strategy for small insects represented by honeybee. This control technique has been confirmed to be effective for honeybee flight initiation and cessation. However, its regulation effect on steering locomotion has not been fully verified. Here, we investigated the steering control effect of honeybee by applying electrical stimulation signals with different duty cycles and frequencies on the unilateral optic lobes and screened the stimulus parameters with the highest response successful rate. Moreover, we confirmed the effectiveness of steering control by verifying the presence of rotation torque on tethered honeybees and the body orientation change of crawling honeybees. Our study will contribute some reliable parameter references to the motion control of cyborg honeybees.

“…Airflow sensors play significant roles in many engineering fields including environmental monitoring, sustainable energy utilization, aerospace engineering and so forth. For instance, the maneuverability and stability of a flying aircraft highly relies on the real-time monitoring and perception of the surrounding airflow conditions [ 1 , 2 , 3 , 4 , 5 , 6 , 7 ]. Moreover, the small size and light weight of unmanned aerial vehicles (UAVs) and micro air vehicles (MAVs) make them susceptible to impact caused by their surrounding airflows [ 3 , 4 ].…”

Airflow sensor is a crucial component for monitoring environmental airflow conditions in many engineering fields, especially in the field of aerospace engineering. However, conventional airflow sensors have been suffering from issues such as complexity and bulk in structures, high cost in fabrication and maintenance, and low stability and durability. In this work, we developed a facile direct-writing method for fabricating a low-cost piezoresistive element aiming at high-performance airflow sensing, in which a commercial pen was utilized to drop solutions of single-walled carbon nanotubes onto tissue paper to form a piezoresistive sensing element. The encapsulated piezoresistive element was tested for electromechanical properties under two loading modes: one loading mode is the so-called pressure mode in which the piezoresistive element is pressed by a normal pressure, and another mode is the so-called bending mode in which the piezoresistive element is bended as a cantilever beam. Unlike many other developed airflow sensors among which the sensing elements are normally employed as cantilever beams for facing winds, we designed a fin structure to be incorporated with the piezoresistive element for airflow sensing; the main function of the fin is to face winds instead of the piezoresistive element, and subsequently transfer and enlarge the airflow pressure to the piezoresistive element for the normal pressure loading mode. With this design, the piezoresistive element can also be protected by avoiding experiencing large strains and direct contact with external airflows so that the stability and durability of the sensor can be maintained. Moreover, we experimentally found that the performance parameters of the airflow sensor could be effectively tuned by varying the size of the fin structure. When the fin sizes of the airflow sensors were 20 mm, 30 mm, and 40 mm, the detection limits and sensitivities of the fabricated airflow sensors were measured as 8.2 m/s, 6.2 m/s, 3.2 m/s, 0.0121 (m/s)−2, 0.01657 (m/s)−2, and 0.02264 (m/s)−2, respectively. Therefore, the design of the fin structure could pave an easy way for adjusting the sensor performance without changing the sensor itself toward different application scenarios.
