2023: Product Announcement
In early October 2023, Russian specialists from the Perm National Research Polytechnic University announced the development of piezoelectric actuators of a new type, which are more than 40 times more efficient than traditional products. The new technology will help make robots stronger and more sensitive.
Piezoelectric actuators are devices based on the reverse piezoelectric effect: they convert an electrical signal into mechanical actions, such as movements. However, traditional products of this type show low efficiency: they consume a lot of energy, while the result of exposure is minimal. Russian researchers have proposed a way to solve the problem.
Perm specialists have developed two types of new piezo devices - membrane (MDS) and shell (CDS) actuators. They use control electrodes in the form of flat or spatial double spirals (DS). These solutions have high efficiency, due to the small distance between the turns of the electrode spiral and the unique "reciprocal" spiral polarization of the piezoelectric layer.
Elements with direct and reverse piezoeffects can be used in modern robotics as "artificial skin" - flexible tactile (sensor) indicator coatings, voice acoustic devices, manipulators for capturing and moving objects. New Russian products will make robots more agile and sensitive to touch.
The actors we have developed open up new prospects for expanding and improving the capabilities of robots. Their speaker systems - microphones and speakers, that is, "hearing" and "voice" - will be more sensitive and louder, and manipulators, that is, "fingers" - more dexterous, stronger. In addition, the "touch" will improve - the feeling of heat, cold and the pressure they produce, which occurs when touching, gripping and manipulating an object, - said Andrei Pankov, professor of the Department of Mechanics of Composite Materials and Structures at PNIPU, Doctor of Physical and Mathematical Sciences.[1]
