For example, the patent application number is 200810203235.5 "a force measuring device and test method for measuring the adhesion force between living organisms and objects", which proposes a force measuring device and testing method for measuring the adhesion force between living organisms and objects using the principle of leverage. However, this test method is complicated in sample preparation, cumbersome in test steps, and the sample platform is fixed, so it can only test the vertical adhesion force, and the test range is small
The patent application number is CN200810156169.0 "Testing method and system for animal foot-surface contact reaction force", which proposes to simultaneously measure the contact between each foot and the attached surface when the animal moves in the horizontal plane, vertical plane and ceiling (suspension position) A test method and system for reaction force, but the arrangement of the sensor array is too cumbersome, and it is only limited to testing animal-surface contact conditions in three special states

Abstract

The invention provides a cantilever beam type measuring device of crawling attaching force of insects or small animals and a method thereof. The measuring device comprises a cantilever beam holder, a strain foil force measuring unit, a sample platform, an xy-axis moving mechanism, a z-axis moving mechanism and a charge coupled device (CCD) imaging system. The method includes tying an insect through a pull thread to one end of the cantilever beam; observing position of the insect and pull force of the insect to the cantilever beam when the insect crawling, conducting overlooking shooting to obtain the projection distance between the insect and a holding hole at the top end of the cantilever beam; conduct side-looking shooting to obtain the vertical distance z between the insect and the holding hole; enabling 4 strain foils in the z-axis direction and 4 strain foils in the y-axis direction to be sequentially symmetrically distributed in double-section alternating mode at the root portion of the cantilever beam and form two bridge circuits and respectively measuring component force of the insect in the vertical downward direction and the horizontal direction. Therefore, the crawling attaching force when the insect crawls or the sample platform descends can be obtained. The device is small in interference and accurate in measurement due to independent action of the insect, thereby being suitable for measurement of the crawling attaching force of the insect.

Description

technical field [0001] The invention relates to a cantilever beam-type insect or small animal crawling force measuring device and method, belonging to the technical field of living organisms and surface crawling force measurement. Background technique [0002] Movement is the basic characteristic of animals and the basis of animal predation, escape, reproduction, migration and other behaviors. The locomotor behavior of animals is the result of the interaction between the animal and the environment under the action of internal force (muscle force). Pods living on the ground realize driving, stabilizing, maneuvering and other motion behaviors through the interaction between the soles of the feet and the ground. Insects such as flies, ants, and crickets crawl quickly on smooth surfaces and can even hang upside down from the ceiling. This has attracted the interest of numerous biologists and has led to extensive research. Studies have found that many insects have sticky crawl...
