STMicroelectronics Releases iNEMO Smart Sensor Technology

January 18 STMicroelectronics (STMicroelectronics, referred to as ST) introduced a new smart garment prototype design with a new ST iNEMO multi-sensor motion co-processor. This design recognizes the complex motion of the user's body and makes it fast and accurate. To digital models. iNEMO Body Movement Reconstruction Technology (iBMR) can improve the clinical and sports treatment as well as enhance the end effect of real-world applications. For example, users can run side by side with world long distance champions on their own track.

By connecting a miniature multi-sensor node to the user's big arm, small arm, big foot, and lower leg respectively, connect two multi-sensor nodes on the back (you can also connect multiple sensor nodes by hand, foot, or head). The prototype of the body motion reconstruction smart clothes design launched by the semiconductor shows the excellent performance of the micro multi-sensor node.

The iNEMO motion coprocessor integrates ST's MEMS motion sensors and magnetic sensors, STM32TM 32-bit microcontrollers, and application-specific software in a solderable 13x13x2 mm micromodule, which is a flexible embedded directional estimation solution Important components.

Using ST's advanced data fusion software, each iNEMO smart sensor node represents the highest performance, smallest size attitude and heading reference system (AHRS) module available on the market. Each multi-sensor node sends data to the controller, and then the controller applies the measurement results to a graphic skeleton model and displays the body movement posture and direction in real time.

Large-scale and complex human motion experiments show that ST’s motion reconstruction smart clothing has excellent detection accuracy and response speed, and the spatial accuracy deviation during the movement is less than 0.5 degrees. The sensor data is processed and applied to the skeleton model. The time is less than 15 milliseconds.
