The birth of bionics is based on the progress of biological science and the mutual penetration with electronics. To consider electronics as the center constitutes bionic electronics. If we take mechanics as the center, we will form bionic mechanics.
Bionic mechanical structure parts have high requirements for materials. These materials have the following characteristics: in addition to corrosion resistance, high strength and high elasticity, they also have lower friction coefficient, higher memory characteristics and higher fracture toughness than traditional materials, and can be machined in batch, etc.
Some studies show that the bulk amorphous alloy materials of some base materials have the above characteristics, which is a competitive choice for bionic mechanical materials.
Flexibility and memory properties, ultra-thin bulk amorphous
Bionic machine is a kind of machine which imitates the shape, structure and control principle of biology, which has more concentrated function, higher efficiency and biological characteristics. The main research fields of bionic machinery include biomechanics, control body and robot.
FESTO is a German enterprise with high attainments in automation technology and bionic technology, especially in the field of bionics. It is famous for all kinds of lifelike robot animals.
Robot bat is made of elastic fiber material 3D printing, it can fly in the air like a real bat. Its wing membrane plays a key role in flight. It is composed of light elastic material and has many similar characteristics with bird feathers.
In order to achieve the degree of refinement, engineers used carbon rods to create its overall structure, and successfully 3D printed its mechanical structure using highly elastic materials.
Bionic opter has become the first robot to simulate the flight status of helicopters, winged aircraft and gliders. Although its design is extremely complex, users can easily control and complete complex flight tasks such as deceleration flight, sudden steering, and even backward flight with smart phones.
Robot ants are about the size of an adult’s palm, much larger than a real ant, and are printed in 3D. The head and the whole body are covered with electric circuits. Ceramic actuators are used in the mouth pliers and leg claws, which can move quickly and accurately. Each ant is a member of “bionic network”. Through wireless network communication, multiple ants can work together to move heavy objects. The ant is also equipped with a conductive wire, which simply presses itself onto the power supply to automatically charge.
Look at the above German bionic machinery, can we find a substitute for bulk amorphous alloy?
