1-. Project description:

The core of the project is he monitoring of human muscle activity. During training the user sees the strength of muscle contractions and adjusts exercise.

2-. Solution:

The final solution will be able to make EMG-measurements for further visualisation. A trainee sees a chart on his device while doing a physical exercise and realises what he/she should adjust for a better training process. The graph has a simple dependency and shows the strength of muscle tension in real-time. During doing a physical exercise the application shows the activity of several muscles simultaneously. And trainee can compare what muscle works harder and improve the training by adjusting the weight of the projectile, the tilt angle and so on. 

During a real-time data comparison, the App could:
a) cause alerts, or/and
b) generate pieces of advice replacing real trainers. The primary task is to get knowledge of data that are generated during muscle measurements (voltage, resistance, etc.). 
 

3-. The Approach:
We investigated several comparable products from different manufacturers and compiled a competitive table with strengths and weaknesses.
IOMICO team concluded that it is better not to overload the hardware, so the cost of the final BoM allowed to expand the possible target audience. IOMICO team designed and produced the PCB, which includes the following components: Nordic nrf 52840; BLE antenna SLDA52-2R510G-S1TF; Accelerometer; ADC ADS1291. From scratch, we developed a firmware that includes BLE pairing/unpairing, EMG measurement and data transferring to smartphones. We expected that the majority of modern users who visit gyms wear smartphones with good performance, so that was the reason why most of the calculations are made by mobile application. In order not to do the same work twice we decided to code in Flutter to create apps for Android and iOS.
