A biomimic voltage field modulation strategy inspired by the cleft of the scorpion compound with the high precision and low power positioning sensor to identify the angles of load incident

Numerous arthropods evolve and optimize sensory systems, which allows them to effectively adapt complex and competitive habitats. In general, scorpions can accurately perceive the location of the dam with the lowest metabolic rate among invertebrates. This biological phenomenon contrasts sharply with engineering systems, which generally associates high precision with substantial energy consumption. Inspired by the sensilla of the cleft of the scorpion compound (SCSS) with a stress field modulation strategy, a bionic positioning sensor with higher precision and a minimum energy consumption is developed for the first time, which uses the units of Minimum particular positioning (MPU) to efficiently locate vibration signals. The unique MPU of the SCSS can recognize the direction of the collinear loads regulating the distribution of the stress field and, in addition, the three MPU coupling action can perform the monitoring of vibrations of the entire angle in the plane. The experiments show that the bionic positioning sensor achieves 1.43 degrees of precision without an angle error without additional energy supply. As proof of concept, two bionic positioning sensors and automatic learning algorithm are integrated to provide location objective of centimeter accessibility (cm), ideal for man-machine interaction. The novel design offers a new mechanism for the design of traditional positioning devices, improving precision and efficiency in the meta-university and real world systems connected to the Internet.
