Bionic lateral-line sensor

A new bionic lateral-line sensor, comprising

• a cilia cupule, a cilia base rod, ionic polymer metal composite (IPMC) film sheets, extraction electrodes, and a sensor housing, wherein
• the cilia cupule is of a hollow structure, and the cilia base rod is disposed inside the cilia cupule;
• the IPMC film sheet is disposed between the cilia base rod and the cilia cupule, wherein the IPMC film sheets comprise a first IPMC film sheet and a second IPMC film sheet;
• the extraction electrode is disposed on each of two sides of a fixed end of each IPMC film sheet;
• and a connection relationship of the four extraction electrodes is a concatenated structure;
• and
• a top end of the cilia cupule, a top end of the cilia base rod, and top ends of the IPMC film sheets are free ends;
• a bottom portion of the cilia base rod and bottom portions of the IPMC film sheets that are fastened inside a groove of the sensor housing are fixed ends;
• and
• the cilia cupule, the cilia base rod, and the IPMC film sheets form a cantilever beam structure;
• and
• when external current acts on a free end of the cilia cupule, mechanical deformation is generated on the cilia cupule, and the mechanical deformation is transmitted to the cilia base rod, so as to cause deformation on the cilia base rod, thereby leading to mechanical deformation on the IPMC film sheets and generating induced voltages.
