Weakly electric fish polarize the nearby environment with a stereotyped electric field and gain information by detecting the changes imposed by objects with tuned sensors. Here we focus on polarization strategies as paradigmatic bioinspiring mechanisms for sensing devices. We begin this research developing a toy model that describes three polarization strategies exhibited by three different groups of fish. We then report an experimental analysis which confirmed predictions of the model and in turn predicted functional consequences that were explored in behavioral experiments in the pulse fish Gymnotus omarorum . In the experiments, polarization was evaluated by estimating the object’s stamp (i.e. the electric source that produces the same electric image as the object) as a function of object impedance, orientation, and position. Signal detection and discrimination was explored in G. omarorum by provoking novelty responses, which are known to reflect the increment in...

对象极化的策略及其在电传感信息收集中的作用。

弱电鱼用定型电场极化附近的环境，并通过使用调谐传感器检测物体施加的变化来获取信息。在这里，我们专注于极化策略作为传感设备的范式生物启发机制。我们将开始研究一个玩具模型，该玩具模型描述三种不同鱼类所表现出的三种极化策略。然后我们报告了实验分析，证实了该模型的预测，并进而预测了在豆类鱼Gymnotus omarorum的行为实验中探索的功能结果。在实验中，通过根据物体的阻抗，方向和位置来估计物体的印模（即与物体产生相同电像的电源）来评估极化。
