Scientists are developing robots with electronic hair that can mimic the touch of human skin and even sense and predict the direction of touch

2022-05-07 15:04:5136kr

Robots are common , Have you ever seen this ?

With electronic hair , It can sense and even predict the touch direction .

Yes , Just like human beings .

Though a little bit “ Black science and technology ”, But Professor of nano electronic material systems at kemnitz University of Technology 、 material 、 Structure and nanofilm integration research center (MAIN) Science director Oliver G. Schmidt The research team led by the professor has explored a new way to develop extremely sensitive and direction related 3D Magnetic field sensors , The sensor can be integrated into the electronic skin system ( Active matrix ) in .

The team used a new approach to achieve 3D Miniaturization and integration of device arrays , And towards Imitate the natural touch of human skin Took an important step .

MAIN Professor Schmidt is a doctoral student in his research team 、 Lead author of the study Christian Becker say :“ Our method allows for 3D Precise spatial arrangement of functional sensor elements in , It can be mass produced in parallel manufacturing process . Such sensor systems are difficult to generate by established microelectronic manufacturing methods .”

Relevant research has been published in the latest issue of Nature Communications The magazine .

Origami technology will 3D Sensors are integrated with microelectronic circuits

The core of the sensor system proposed by the research team is the so-called Anisotropic magnetoresistance (AMR) sensor .

AMR Sensors are mainly used to accurately determine The magnetic field The change of , At present, it is mostly used for speed sensors in cars , Or determine the position and angle of moving parts in various machines .

In order to develop a highly compact sensor system , The researchers used the so-called “ Micro origami Technology ”(micro-origami process). This process is used to convert AMR The sensor assembly is folded into a three-dimensional architecture , It can analyze the three-dimensional magnetic field vector field . Micro origami allows a large number of microelectronic components to be installed in a narrow space , And arrange them into geometric shapes that cannot be realized by any traditional micromachining technology .

“ Micro origami technology was developed in 20 Many years ago , It's nice to see that the full potential of this technology can now be used in new microelectronic applications .”Oliver G. Schmidt The professor sighed .

The research team will 3D The micro origami magnetic sensor array is integrated into a single active matrix , Each individual sensor can be easily addressed and read through microelectronic circuits .

“ The combination of active matrix magnetic sensor and self-assembled micro origami architecture is a new method , High resolution can be 3D Miniaturization and integration of sensing system .”Daniil Karnaushenko Doctor said , He was interested in the concepts in the project 、 Both design and implementation have made a decisive contribution .

Tiny hairs predict and sense the direction of touch in real time

according to the understanding of , The research team has successfully transformed 3D The magnetic field sensor is integrated into the artificial electronic skin .

Electronic skin is made of elastic material , Electronic devices and sensors are embedded , This is similar to organic skin intertwined with nerves .

When the hair is touched and bent , At the bottom 3D The magnetic sensor can detect the movement and exact position of the magnetic root . in other words , The sensor matrix can not only record the bare movement of hair , You can also determine the exact direction of motion . Like real human skin , Every hair on the electronic skin becomes a complete sensor unit , Can sense and detect nearby changes .

3D The real-time magnetic mechanical coupling between magnetic sensor and magnetic hair root provides a new type of touch sensitive sensing through electronic skin system . When humans and robots work closely together , This ability is very important . for example , Robots can make contact intentionally or before an accidental collision is imminent , Early perception of interaction with human companions , And provide many details .

Anthropomorphism of robots

In recent years , The anthropomorphism of robots has gradually become a new development trend .

Such as the UK Engineered Arts The robot launched by the team last year Ameca, The team calls it “ The future side of Robotics ”, It represents the highest level of human robot technology .

Look at this, it's like CG The same action expression as the special effect , No wonder many netizens think of the horror valley effect .

according to the understanding of , The hardware and software of the robot are modular , It's easy to upgrade iterations , It can also run independently , in other words , Sometimes we don't even need a complete robot , Can only control the head , Or arms , You can complete the requirements .

Project team introduction ,AI At present, it is usually only at the code level , Not as dramatic as a lifelike finished robot . But at the software level , With AI Accumulation of simulation expression technology at the program and hardware levels ,Ameca Can build instant rapport with anyone .

at present Ameca The full range of sports equipment is also limited to the upper body , The lower body is still under development .

besides ,2021 year , Creative machine laboratory in the United States (CreativeMachines Lab At Columbia Engineering) Published about EVA Research on robots . The new robot has a soft and expressive face , Can respond to smiles and other expressions .

according to the understanding of , The team used 3D Print to make parts , These precise and complex parts and EVA Our skulls are seamlessly joined together . After weeks of debugging ,EVA Can make a smile 、 A frown or an expression that looks upset , These expressions have some authenticity . And then , Researchers began to guide EVA Use artificial intelligence to program facial motion , adopt “ watch ” Facial expression videos , Through AI “ read ” Other people's expressions , Then reflect it on yourself “ face ” On .

Just like this. :

1970 year , Depict how humans feel about robots and non-human objects Valley of terror effect available . The theory points out that , If an entity “ Not human enough ”, Then its humanoid characteristics ( Like the face of a plush doll ) Will be visible and easy to identify , It's easy to get human favor . contrary , If an entity “ Enough personification ”, Then its non human characteristics will become a prominent part , Produce a strange feeling in the eyes of human observers .

Now , With the progress of science and technology , Based on the valley of terror effect , In a field more realistic than humanoid robots , Some research results will be classified as the bottom of the valley of terror , It gives people that creepy feeling .

But maybe one day , The valley of terror effect will be surpassed with the development of technology , We will see .
