“…When the proposed hair sensor is arranged in the oscillatory air flow, the frequency difference of the DETFs is also an alternating current signal that requires a specific demodulation scheme [12]. In this paper, a demodulation approach based on the minimization criterion of the mean square error is proposed to extract the effective signal from the noise signal, as shown in Figure 8.…”

“…Through the traditional second lever, it forms the two-stage microleverage mechanism, which aims to increase the sensitivity of the signal detector by amplifying the resistance. In [12], inspired by the fish lateral line system, an artificial lateral line system based on the bionic hair sensor with a resonance readout was designed by using this structure. Compared with the signal from a single hair releasing sensor, the biaxial velocity measurement is realized by different array distributions.…”

This paper presents the design, theoretical analysis, simulation verification, fabrication and prototype characterization of a novel biaxial bionic hair flow sensor based on resonant sensing. Firstly, the device architecture, mainly consists of a polymer hair post, a silicon micro signal transducer and a glass substrate, is described, the theoretical simplified model is established and the mechanical sensitivity to air flow is deducted. Then, the structure simulations based on Ansys software are implemented to preliminarily verify the feasibility of the proposed sensor conception and optimize the structure parameters simultaneously. Subsequently, a closed-loop control scheme based on digital phase-locked loop and an amplitude demodulation algorithm of oscillatory flow velocity based on the least mean square method are proposed to transform and extract the air flow signal, and then verify it by circuit simulations based on SIMULINK. Finally, the fabricated prototype is illustrated and comprehensively tested. The tested prototype possesses an x-axis scale factor of 1.56 Hz/(m/s)2 and a y-axis scale factor of 1.81 Hz/(m/s)2 for the steady air flow and an x-axis detection threshold of 43.27 mm/s and a y-axis detection threshold of 41.85 mm/s for the oscillatory air flow.

“…These sensors employ thermally dependent resistors in the form of nanowires placed in the flowing fluid, where the flow of the fluid cools the suspended nanowires, allowing for the measurement of fluid flow velocity. Most of these artificial sensors fundamentally rely on the strain induced by the deflection plate or cantilever structure at the bottom to respond to fluid flow [10]. This design avoids some unnecessary boundary layer effects [11].…”

Developing an all-optical continuous two-dimensional force sensing platform with microforce detection and direction recognition is a challenging task. In this paper, we propose a novel structure of a photonic two-dimensional force perceptron based on fiber Bragg gratings (FBGs) for the first time to demonstrate microforce detection and direction recognition in an all-optical transmission sensing platform. It consists of silicon gel covering arranged in equilateral triangles with specific side lengths on a fiber Bragg gratings (FBGs). The force stimulation is sensed by stress transfer ball located on top of the perceptron, and the force is transmitted to three Bragg gratings arranged in equilateral triangles through the encapsulation material. The perceptron can achieve force detection with a sensitivity of 0.06mN and a force stimulation resolution of 0.1mN . The reset operation mainly relies on the high elastic modulus of the material itself. The results demonstrate continuous optical sensing of microforce stimulation ranging from 0mN to 2mN ,In addition, we presented the results of large-scale directional force stimulus recognition, successfully achieving directional recognition of force stimuli. Furthermore, we achieved angle recognition with an error rate of 1% , prove the practical potential of constructing a precise positioning continuous all-optical force sensing platform. Hopefully ,this research can provide experimental basis and operating experience for all-optical two dimension force stimulus recognition sensing platform.

“…The hair-like sensor can realize the effective measurement of linear/angular velocity, acceleration, and other information so that it can be widely used in lateral line systems, inertial navigation systems, flow sensing, situation awareness, and so forth. According to the different realization principles, the hairlike sensor can be divided into piezo-resistive [5][6][7][8], capacitive [9][10][11], piezoelectric [12,13], resonant [14][15][16][17][18][19], and so on [1,3,4]. Resonant sensors can realize quasi-digital signal output, which can effectively avoid the problem of low measurement accuracy caused by analogto-digital conversion.…”

Compared with lever-type amplification mechanisms, bridge-type flexible amplification mechanisms have advantages in terms of amplification ratio and structural compactness. Therefore, they can effectively replace the lever-type amplification mechanism in the existing hair-like sensors and realize the development of miniature hair-like sensors with high sensitivity. With that in mind, a highly sensitive hair-like sensor based on a bridge-type amplification mechanism with distributed flexibility is presented to measure the airflow rate. First, the structural composition and operating principle of the hair-like sensor are described. Then, detailed design and analysis of the hair-like sensor are carried out, focusing on the design of the hair post structure, amplification mechanism, and resonator. Furthermore, the designed hair-like sensor is processed and prepared, and some experimental studies are conducted. The experimental results demonstrate that the developed hair-like sensor can measure the airflow rate with high sensitivity up to 8.56 Hz/(m/s)2. This provides a new concept for the structural design of hair-like sensors and expands the application of bridge-type flexible amplification mechanisms in the field of micro/nano sensors.
