Xiaoqiang, who can't die, transforms into a "semi -mechanical cockroach"?Please allow me to honor a strong brother

Cockroaches, which are often called "Xiaoqiang", are a strange creature that everyone hates gritting teeth and wanting to get rid of it.

Why is it strange? It is because cockroaches have a strong vitality and fertility, which has a history of hundreds of millions of years. Under the crackdown of countless human beings, it can still survive stubbornly.

According to modern biological classification, there are about 4,000 cockroaches on the earth, of which only dozens of types will invade human homes. museum.

Among the most common cockroaches, the American cockroaches (Periplaneta Americana), Australian cockroaches (Periplaneta Austrasiae) and short-winged spots (NEOSTYLOPYGA RHOMBIFOLIA) are larger, with a body length of about 2-4 cm; Blattella (Blattella (Blattella Germanica, Japanese Blattella Bisignata and Blattella Asahinai are small, with a body length of about 1-2 cm.

Under normal circumstances, cockroaches in tropical areas are relatively large and can reach 10 cm in length, such as Blatta Orientalis.

However, small cockroaches are also useful, such as being deployed in search and rescue tasks, or investigating places that are more dangerous.

The demand for remote control and long -term battery life has always been a problem that has not been solved. Today, this idea may soon become a reality.

Recently, the research team and collaborators of the CLUSTER for Pioneer Research (CPR) and their collaborators of the Institute of Physics and Chemistry (CPR) designed a system that can create remote control semi -mechanical cockroaches.

As shown in the figure above, is it very technological?

According to reports, the system is equipped with a miniature wireless control module that can be charged by solar energy, which can achieve self -power supply, and ultra -thin electronic equipment and flexible materials can make semi -mechanical cockroaches move freely.

The research team believes that the advent of semi -mechanical cockroaches may make the application of semi -mechanical insects possible in real life.

Related studies are published on the title of "Integrating of Body-Mounted Organic Solar Cell on Cyborg Insects with Intact Mobility".

For a long time, semi -mechanical insects are considered to be used to monitor dangerous areas or surrounding environments, but to make this idea a reality, the semi -mechanical insects need to be controlled for a long time. In other words, the operator can control the legs of the semi -mechanical insect wirelessly and use solar energy to power it for a long time.

However, it is not easy to achieve the above functions.

In order to integrate these devices into the limited surface area of ​​cockroaches, the research team needs to develop a special "backpack", an ultra -thin organic solar cell component, and a adhesion system that ensures the semi -mechanical cockroach free movement.

In this work, the research team will use the 6 cm Madagascar Cockroach as an experimental object, and use a specially designed cockroach model backpack to connect the wireless leg control component and lithium polymer battery to the top of the insect chest Essence

According to the paper, this backpack is printed with a elastic polymer 3D, which is completely in line with the "body shape" of cockroaches, which can be fixed for more than a month on the chest of cockroaches.

In addition, the ultra -thin organic solar battery component is only 0.004 mm thick, and is installed on the abdomen side of the cockroach. Its output power is 17.2 mile, which is more than 50 times larger than the currently advanced insect energy collection equipment.

Ultra -thin, flexible organic solar cells, and its attachment methods can ensure that semi -mechanical cockroaches are free for a long time.

After careful inspection of the natural movement of cockroaches, the research team found that the abdomen of cockroaches will change the shape, and some exoskeleton will overlap. In order to adapt to this situation, they used sticky and non -sticky materials, so that solar cells can be bent and attached.

When testing a thicker solar cell film, or when the film is evenly attached to the abdomen of the cockroach, it takes twice the same distance to run the same distance, and it is difficult to turn over.fail.Figure ｜ Semi -mechanical cockroaches that cannot be turned over.(Source: NPJ Flexible Electronics)

At the end of the paper, the research team also said, "Because abdominal deformation is not unique to cockroaches, our strategy can adapt to other insects such as beetles, and may even be used on flying insects like cicada in the future."
