Annotation: This research presents the morphological features by using SEM, TEM of the insect Nabis rugosus mechanoreceptors especially trichoid sensilla which detects various tactile factors that surrounds the insect. The reconstruction of 3D model of trichoid sensillum of insect Nabis rugosus by using AMIRA software was done. This study presents a model and simulation of trichoid sensilla sensing mechanism in which the hair deflects due to applied external force over it and presses the dendrite sheath attached to hair base where dendrite sheath is displaced by the applied force, transforming the transversal loading into a longitudinal deformation of the microtubules. Due to this longitudinal deformation, electric potential develops in the microtubule’s core, and information is delivered to the brain through the axon. The numerical model of trichoid sensilla of insect Nabis rugosus was developed and the structural,modal and electrostatic analysis were analyzed. Based on the morphology and sensing mechanism of trichoid sensilla of insect Nabis rugosus developed the design of Bioinspired hair like sensor using direct iteration optimization procedure and the structural,modal and electrostatic analysis were performed and the resutlts were analyzed by comparing with the trichoid sensilla of insect Nabis rugosus.And, the novel manufacturing procedure were proposed for the fabrication of Bioinspired hair like sensor. This thesis summarizes the research methodology,design and analysis,results achieved and their conclusions.
