In this study, we fabricated a novel wearable vibration sensor for insects and measured their wing flapping. An analysis of insect wing deformation in relation to changes in the environment plays an important role in understanding the underlying mechanism enabling insects to dynamically interact with their surrounding environment. It is common to use a high-speed camera to measure the wing flapping; however, it is difficult to analyze the feedback mechanism caused by the environmental changes caused by the flapping because this method applies an indirect measurement. Therefore, we propose the fabrication of a novel film sensor that is capable of measuring the changes in the wingbeat frequency of an insect. This novel sensor is composed of flat silver particles admixed with a silicone polymer, which changes the value of the resistor when a bending deformation occurs. As a result of attaching this sensor to the wings of a moth and a dragonfly and measuring the flapping of the wings, we were able to measure the frequency of the flapping with high accuracy. In addition, as a result of simultaneously measuring the relationship between the behavior of a moth during its search for an odor source and its wing flapping, it became clear that the frequency of the flapping changed depending on the frequency of the odor reception. From this result, a wearable film sensor for an insect that can measure the displacement of the body during a particular behavior was fabricated.

耳式振动传感器，用于测量昆虫的翅膀拍打

在这项研究中，我们为昆虫制造了一种新型的可穿戴式振动传感器，并测量了它们的翅膀拍动。对与环境变化有关的昆虫翅膀变形的分析在理解使昆虫能够与其周围环境动态交互的基本机制方面起着重要作用。通常使用高速摄像机来测量机翼的拍动；但是，由于该方法采用间接测量，因此难以分析由拍打引起的环境变化引起的反馈机制。因此，我们提出了一种新颖的薄膜传感器的制造，该薄膜传感器能够测量昆虫的翅膀频率的变化。这款新颖的传感器由混合了有机硅聚合物的扁平银颗粒组成，当发生弯曲变形时，它会改变电阻的值。将传感器安装到蛾和蜻蜓的翅膀上并测量其拍打的结果，我们能够高精度地测量拍打的频率。另外，作为同时测量蛾在寻找气味源期间的行为与其翅膀拍打之间的关系的结果，很明显，拍打的频率根据气味的接收频率而改变。根据该结果，制造了可测量昆虫在特定行为期间身体的位移的可穿戴膜传感器。我们能够高精度地测量拍打的频率。另外，作为同时测量蛾在寻找气味源期间的行为与其翅膀拍打之间的关系的结果，很明显，拍打的频率根据气味的接收频率而改变。根据该结果，制造了可测量昆虫在特定行为期间身体的位移的可穿戴膜传感器。我们能够高精度地测量拍打的频率。另外，作为同时测量蛾在寻找气味源期间的行为与其翅膀拍打之间的关系的结果，很明显，拍打的频率根据气味的接收频率而改变。根据该结果，制造了可测量昆虫在特定行为期间身体的位移的可穿戴膜传感器。
