A reliable research and clinical partner sold across the world since 2012

Waterproof, miniaturised, Wave Plus wide range of surface EMG sensors answers to most researcher’s needs.

Leading EMG technology

Released in 2012, as the natural evolution of the Wave technology. Wave Plus system includes a receiving unit with analog and digital output, and a charging station compatible with all our wireless sensors. Wave Plus introduced several improvements over the previous product, and added some new exclusive features:

  • Impedance check control for pre-acquisition quality monitoring
  • Improved wireless transmission (up to 300% improvement)
  • Flexibility to use more than EMG sensors (including general analog sensors, IMUs, FSW)
  • Analog output with 66 connections and 14 ms fixed delay

One hub, several solutions

You can use Mini, Pico, or WaveTrack sensors with the Wave Plus systems, mixed and matched as per your requirements.

WaveTrack IMU

UP ro 280Hz sampling, fused or raw data, 8 hours of battery life and data logger.

Mini Wave EMG

Longest range, replaceable battery, waterproof capability.

Pico EMG

The smallest EMG sensor on the market with 10 hours of battery life and unparalleled ease of use.


Using the years of experience producing Zerowire and servicing all the units sold worldwide, Wave Plus comes with all the improvements needed for an up-​to-​date wireless EMG system. The most important exclusive features are the following:

  • Up to 32 channels simultaneously
  • Simultaneous output of all data both via USB and analog interface
  • Impedance check function on each electrode to assess if the level is low enough to get high quality data
  • Sensor batteries inductively recharged
  • Inter-​probes latency <5 usec (less than 5 microseconds)
  • CE 93/42 class I certification and production under ISO:13485 standards

Fixed delay

All our EMG sys­tems have been devel­oped in order to have a fixed delay from the acqui­si­tion of the sig­nal to the ana­log out­put.

Diversity receiver

The «Diver­sity Mode» tech­nol­ogy used by our EMG sys­tems min­i­mizes the effect of wave reflec­tions from walls or objects.

Impedance check

Exclu­sive sys­tem devel­oped by Cometa that auto­mat­i­cally checks the imped­ance of the skin dur­ing the pre-​acquisition phase.

Inductive charge

The inductive recharge technique for EMG and inertial transmitter has been develop by Cometa and has been used in all our systems since 2005.

Analog 66

The only one in the EMG world that can carry out the data of sixty-​six
chan­nels simul­ta­ne­ously.


Wave Plus EMG is fully compatible with our own EMG and Motion Tools software, which is the only software for EMG acquisition provided FREE of charge with the purchase of any EMG system. This software is simple and yet powerful at the same time, allowing you to:

  • Up to 32 channels of EMG or IMU data simultaneously
  • Gyro, Accelerometer and Magnetometer raw data
  • View and replay inertial data
  • EMG system configuration with .cfg files
  • Save the data in .c3d format
  • Export all data in ASCII format (.txt)
  • Import data saved on the memory on board
  • FREE installation

Tennis practice recording with IMUs and EMGs

This is our new promo video showing the features of our latest EMG and IMU models. We recorded full body IMU with joint angles, 8 ch EMG, and 8 EMG + 7 IMU lower body. All of it in a real practice setting, outdoor, with easy setup and no distance limitations. www.cometasystems.com


Biomot European Project

This video is a summary of the Biomot EU FP7 Project. We recommend to all the audience interested in wearable robotics and biomechanics to watch full video. Technaid’s exoskeleton Exo-H2 has been used for different tests along the project and the inertial technology for subject’s biomechanical analysis was provide by Technaid too.

The main objective of the project was to improve existing wearable robotic exoskeletons exploiting dynamic sensory-motor interactions and developing cognitive capabilities that can lead to symbiotic gait behaviour in the interaction of a human with a wearable robot.


Mini Wave and WaveTrack Waterproof IPX7 certified EMG and IMU sensors

Our EMG and IMU sensors are the only ones on the market that can work underwater. In the video, an athlete performs several tasks, including underwater gait (ideal for rehabilitation research), and fast swimming in different styles. All data is logged on board the sensors and downloaded later. Customers include Japan Institute of Sports Science and Edinburgh University. Contact us for more information and a quote.
