Abstract

A sliding temperature tactile sensing device is provided with a temperature sensing unit array, a heat conduction layer, a constant temperature layer, a heat insulation layer, a heat insulation shell, and a measurement and control circuit. The temperature sensing unit array includes a plurality of temperature sensing units, and each temperature The sensing unit is equipped with a thermistor, a heat conduction cap and a spring, the thermistor is placed in the heat conduction cap, the lower end of the spring is sleeved on the open end of the heat conduction cap, and the heat conduction layer is provided with a through hole corresponding to the temperature sensing unit , the closed end of the heat conduction cap is in the through hole and protrudes from the lower surface of the heat conduction layer, the lower surface of the constant temperature layer is provided with a blind hole corresponding to the temperature sensing unit, and the bottom of the blind hole is provided with a through hole smaller than the diameter of the blind hole through the constant temperature layer On the surface, the upper end of the spring is embedded in the blind hole and pressed against the bottom of the blind hole, and the metal heating wire is wound on the side surface of the constant temperature layer. They are all placed in the heat-insulating shell, and the plane of the opening at the lower end of the heat-insulating shell is flush with the lower surface of the heat-conducting layer.

Description

technical field [0001] The invention relates to a sliding temperature tactile sensing device, which can distinguish the thermal properties of materials and the sliding direction, and is suitable for many fields such as remote operation robots and space detection, and belongs to the technical field of tactile sensors and temperature sensors. Background technique [0002] With the widespread application of virtual reality technology and interactive teleoperation robot technology, a large number of tactile sensing and reproduction devices are required to achieve the effect of "multi-sensing, interactivity and presence". So far, research on haptics at home and abroad has mainly focused on force haptics. The application of continuously optimized force haptic algorithms in flexible and textured haptic reproduction devices enables these devices to better reproduce the flexibility and texture of objects in virtual scenes. The tactile properties of texture and force, but the research...
