Beijing Shenmou Technology Co., Ltd. recently released a rare high-precision piezoelectric six axis force sensor in the industry, called "Bounce", which is particularly suitable for service robots, humanoid robots, aerospace, medical, industrial automation and other scenarios that require high dynamic interaction and multi-dimensional force control in the environment. This product has fast response, high stiffness, high frequency bandwidth, anti electromagnetic interference, and wide area environmental adaptability, marking Shenmou Technology's continuous breakthrough in the field of intelligent sensor technology.
Piezoelectric "pop-up" six axis force sensor: working principle and technical advantages
This sensor is different from traditional strain gauge six axis force sensors. It is based on the piezoelectric effect principle of piezoelectric materials, and measures by converting applied mechanical energy into electrical energy. It has fast response and high dynamic performance, and is particularly suitable for complex working conditions such as humanoid robots and aerospace that require precise control and real-time feedback.
The piezoelectric six axis force measurement system of Shenmou Technology is equipped with the industry's first miniaturized intelligent signal decoupling device, integrating multiple signal acquisition modules and intelligent data processing units, which can achieve precise decoupling of force and torque signals in different directions. By independently processing and analyzing the charge signals in different regions, high-precision separation and output of six axis force signals can be achieved.
Core performance characteristics
High precision measurement: Accurately capturing force information in the X, Y, and Z directions and torque information around the three axes, meeting the force control requirements of the dexterous hand joints of humanoid robots.
Quick response capability: The piezoelectric effect endows the sensor with extremely fast force feedback speed, making it suitable for high dynamic applications such as high-speed impact testing, vibration analysis, and instantaneous collision detection.
Strong stability: Piezoelectric materials themselves have good thermal and structural stability, ensuring long-term reliable performance of sensors in various complex environments.
High initial load tolerance: Charge discharge operation can be performed to reset the input of the charge amplifier to zero, thereby avoiding the impact of high initial load. Supports 300% overload capacity, and can accurately perform subsequent incremental force measurements even under initial load conditions exceeding the rated range.
Ultra high frequency response capability: It can accurately capture instantaneous small vibrations and high-frequency impacts, such as the recognition of instant contact between service robot end effectors and hard objects.
High stiffness and low hysteresis: The sensor structure has high rigidity and minimal deformation, effectively suppressing hysteresis errors. The hysteresis error is less than 0.2% FS, making it suitable for high-precision scenarios such as rocket engine vibration testing.
Wide environmental adaptability: Adopting high-temperature resistant packaging technology, it can work stably in the temperature range of -200 ° C to+400 ° C, and has the ability to resist radiation, impact, and humidity.
Anti electromagnetic interference capability: By directly outputting signals through charges, without the need for traditional bridge circuits, it can operate stably even in strong electromagnetic environments (such as motor drives).
Maintenance free and long-term reliability: Piezoelectric components have no moving parts, possess high mechanical strength and long lifespan, and are suitable for long-term continuous operation in industry.
