Description
Technical Field
The invention relates to the field of biological simulation or artificial skin, in particular to an implantable bionic sweat gland with rigid characteristics and an intelligent robot.
Background
Artificial skin (Artificial skin) is mainly classified into two major categories, one is Synthetic skin (Synthetic skin) and one is Smart skin (Smart skin). The intelligent skin is an important research field of man-machine interaction and artificial intelligence, and the intelligent skin also plays an important role in the medical health field.
At present, all components of the flexible sensor except the electrodes are made of flexible materials, and due to the complexity of the skin, a small local area can often achieve multiple functions, especially a sense function, and sense cold, heat, softness and hardness, so that the bionic thinking for electronic skin in recent years is to laminate the skin and install different types of sensors on each layer of the skin. The prior art discloses a multi-layer electronic skin, wherein a first layer of skin is composed of a first hydrogel and a plurality of first sensors, a second layer of skin is similar to the first layer of skin in construction mode, and the outer part of a first flexible hemispherical convex pressing plate and the outer part of a second flexible hemispherical convex pressing plate in the second layer of skin are opposite to each other. The upper layer skin and the lower layer skin are contacted through the flexible hemispherical convex pressing plate, the contact area is small, and the electronic skin provided by the scheme has high sensitivity because the electronic skin can quickly respond when being stimulated by the outside. However, the high temperature environment affects the performance and service life of electronic components and equipment, and the traditional convective heat exchange method and forced air cooling method which rely on single-phase fluid have difficulty in meeting the heat dissipation requirements of many electronic components.
Lee et al utilize the bionic sweat gland of nanometer clay and temperature-sensitive hydrogel preparation, not only realized through water evaporation cooling's function when the temperature is high, still realized simultaneously preventing water evaporation's function when the temperature is low. However, such biomimetic sweat glands with micro-surface structures still have drawbacks in terms of stability, implantable, and especially heat transfer efficiency.
Rob Shepherd, university of Conneler, and its research team developed a special material for the palm of a robot that could control the temperature inside the machine in a "sweat-secreting" manner. However, the bionic sweat gland using sweat as a heat dissipation mode has defects, namely, the external shell can become wet and slippery in the process of completing heat exchange by sweat discharge, the due friction force of the artificial sweat gland is reduced, the artificial sweat gland is unfavorable for grasping, objects in hands can slide down, and the appearance can become wrinkled although the texture of an upper layer is modified to be relieved in the aspect. In addition, the current robot needs to supply water regularly to supplement the evaporated water. Therefore, the heat dissipation mode of simply discharging water and sweating can not control the water yield due to the change of the opening sizes with different temperatures, so the stability of heat dissipation is not controllable. The water supply is discharged once, and the discharged water can not be collected for recycling in the using process, and the surface state of the outer palm can be changed, so that the surface becomes wet and slippery, and the grasping process is not facilitated.
Researchers in the university of kyoto japan have adopted the mode of bionic sweat glands in the cooling mode of kengloro robots to develop more efficient coolant delivery systems. Kengoro is internally provided with an aluminum frame, and the frame is provided with gaps and channels similar to sponge. These channels can transport water throughout the robot and achieve heat exchange by evaporation, and aluminum frame based cooling systems sweat just like humans. Tests show that the perspiration technology is 2 times better than the traditional cooling mode. The micro-surface structure is a rigid structure, is arranged in the robot, is unfavorable for the whole body of the robot to be provided with skin covering, evaporates liquid and is scattered into the air, and the micro-surface structure can not be collected and recycled.
