The Paris Olympics came to an end, and Chinese athletes concluded their journey successfully. Sports competition is not only a challenge of physiological limits, psychological tactics of confrontation, but also the embodiment of scientific and technological assistance and the results of continuous training. How can science and technology help athletes improve their "power"?
Flexible Pressure Sensor
The invisible assistant indispensable for future sports training
The VBT system used in weightlifting training, isokinetic muscle strength equipment in boxing, and double-plate force measurement platforms in sprint training all rely on high-sensitivity force sensors to achieve accurate training tests.
With the outstanding advantages of small volume, wide range, high sensitivity and high pressure resolution, flexible pressure sensors are able to accurately capture the small pressure changes of athletes in training, and accelerate the expansion of applications in the field of sports, which in the future will become an indispensable and invisible assistant in athletes' training, providing valuable data support for sports training.
Small size, suitable for any surface
Gymnasts need to control each movement precisely, the flexible pressure sensor is extremely miniature and can be mounted on any surface (including sports clothing) without affecting the experience. With a pressure detection range of 0~2MPa, it can monitor small pressure changes, and monitor the accuracy of the athlete's movements and strength distribution in real time.
Simulation scenarios for localized movement detection in gymnastics:
Any subtle movement made by a foot wearing a normal sock stepping on an array of flexible perceptual force sensors can be detected by the sensors as a change in pressure at the corresponding foot position.
Penetrating monitoring to enhance technical movement
Pressure changes in the soles of the feet and hands of track and field athletes and ball players are crucial to movement adjustment. The high sensitivity and high resolution flexible pressure sensor has been verified to have the ability to penetrate through insoles, gloves and other objects to monitor pressure changes in different areas of the soles of the feet and hands, helping athletes to enhance their technique and improve their overall performance.
Running monitoring simplifies simulation scenarios:
The tester stood on the flexible pressure sensing array wearing sports shoes with a similar pressure distribution on both feet. When supported on one foot, the pressure range of the supporting foot was extended and the pressure was enhanced, and the results were the same for the opposite situation.
Adapts to multiple communication methods
The flexible pressure sensor supports a variety of communication protocols such as IIC, UART, IO, etc. It is compatible with the communication speeds of different hosts, and it takes only 100 milliseconds to start up, with a refresh frequency of up to 100Hz, which provides technical support for the direct connection between the intelligent terminal and the motion detection equipment assembled with the sensor.
Low power consumption, environmental protection and energy saving
Flexible pressure sensor working voltage is 3.3V, the maximum working current is 10mA, low energy consumption; the product weight is less than 1g, the material is in line with RoHS standards, in line with the development trend of environmental protection and energy saving of sports equipment.
With the continuous maturity of the technology and the continuous expansion of the application, in the future field of sports and athletics, flexible pressure sensors will certainly play a more important role as a scientific and technological force to promote the development of sports.
