iBody Smart EMS Training System โ Product Overview (Current Model)
The iBody Smart EMS Training System is an advanced full-body fitness solution designed to deliver professional-grade Electric Muscle Stimulation (EMS) training from the comfort of your home or gym. Engineered for efficiency, the iBody system stimulates all major muscle groups simultaneously, offering a complete workout in just 10 to 20 minutes once a week.
This existing model features a compact, high-performance EMS controller paired with a wearable EMS suit that ensures precise muscle activation across 8 independent output channels. The system is easy to use, wirelessly controlled via a dedicated mobile app, and supports various training modes such as Fat Burn, Strength, Recovery, and Massage.
Key Features of the Current Model:
-
8-channel EMS stimulation for full-body training
-
Mobile app control for real-time intensity and mode adjustment
-
Compact design with rechargeable battery
-
Suitable for all fitness levels โ beginner to advanced
-
German-developed technology with medical-grade standards
We are currently working on the next-generation iBody system, which will feature the powerful ESP32-S3 microcontroller, enabling improved Bluetooth connectivity, OTA firmware updates, enhanced signal precision, and overall system reliability.
This is the product we are actively improving โ the new version will deliver even greater performance, control, and user experience.

Links to All Resources & Documentation
Below are the essential files and documentation required for engineers and developers working on the iBody Smart EMS Training System:
PCB Layout โ iBody Smart EMS Controller
The PCB layout for the current iBody EMS controller includes 8 output channels, a boost converter for 3.7V LiPo battery power, and is based on the ESP32-S3 microcontroller. The design follows a compact 4-layer structure, optimized for high-frequency signal integrity and minimal EMI.
Engineer needs to verify the PCB file before approving it for production.
Firmware โ iBody Smart EMS Controller (ESP32-S3)
This firmware controls the electrical output signals of the iBody EMS device, communicates with the mobile app via BLE (Bluetooth Low Energy), and manages all workout parameters in real time. The firmware is developed for the ESP32-S3microcontroller and is OTA (Over-The-Air) update ready.
All Details Overview
Full documentation is available in the shared Google Drive, organized into 6 folders โ each containing a different PCB model with the same EMS functionality.
The latest version, found in Folder 6 โ BodyTech, features the ESP32-S3 microcontroller and serves as the base for the new iBody system.
The engineer must verify all PCB files, focusing on the BodyTech version, before giving final approval for production. Schematics, layouts, BOMs, Gerber files, and pick & place data are included.
eSuit
An 80% Nylon + 20% Spandex blend is a standard, high-performance fabric for EMS suits.
It provides the durability, stretch, and skin contact required for optimal electric impulse transmission while being comfortable, breathable, and long-lasting.
Backend CRM X
The unified backend powering the iBody Smart EMS Training System and CRM X.
It manages user accounts, workout sessions, EMS devices, subscriptions, and business operations โ all in one secure, scalable platform.
