STMicroelectronics, a semiconductor solutions provider, has revealed the prototype of a smart suit embedded with the ST iNEMO motion co-processor. Designed to identify complex body movements, the iNemo multi-sensor nodes, the smallest in the market, translates the data into a digital model with unparalleled speed and accuracy.

The Body Motion Reconstruction technology of iNEMO, iBMR provides better outcomes in sports medicine and clinical applications while vastly improving the augmented reality for the end-user experience. In the present prototype of the body suit designed for motion reconstruction, the miniature iNEMO sensor nodes demonstrate optimal performance with two nodes attached on the back, one each on the arms, forearm, calf and thigh. Additional multi-sensor iNEMO nodes can be mounted onto the head, shoes or hands.

The iNEMO motion co-processor integrates magnetic MEMS sensor and motion sensors with the STM32 microcontroller and software in a solderable module of 13 x 13 x 2 mm. The small form factor makes the co-processor a flexible solution for embedded orientation estimation applications.

Using data fusion software, every iNEMO sensor node signifies a high-performance Attitude and Heading Reference System (AHRS) module, which are capable of transmitting sensor data to the control unit. The control unit applies the calculations to a graphic skeleton model and displays the corresponding body motions in real-time.

STMicroelectronics has conducted exhaustive tests with complex body motions and verified the speed and precision with which the body motion-reconstruction suit applies the data to the graphic model of the skeleton. During the testing, spatial accuracy deviation of less than 0.5 degrees occurred during movements and the process was complete in fewer than 15 ms.
