Our original accessories, to customise our EMG or IMU products to your specific needs.

Remote controller

The remote controller can be used to start/stop a remote acquisition (with Mini Wave Infinity) whenever using a PC is not feasible or not possible. Remote controller is necessary to start and stop underwater acquisitions, being the only way to start an asynchronous data logging session.

BNC patch panel

The BNC patch panel from Cometa allows the connection between the analog output of Wave or Wave Plus systems to any acquisition board using BNC connections. This interface can be provided with 18 outputs (for Wave systems) or 66 (for Wave Plus systems).

Finewire probe

This probe can be used to interface with any certified electrodes that accept a free wire connection. In most cases this is used with Finewire needles for intramuscular EMG acquisitions. The probe is custom built with a 10-1000 Hz Band-Pass frequency, an extra 500 Hz of bandwidth compared with our regular surface EMG probes.

Trigger box

Provided with ALL our EMG systems, this box allows you to:

  • Synchronize two Wave or Wave Plus systems to obtain a total number of channels up to 32
  • Synchronize with virtually all systems accepting a TTL trigger with a BNC cable
  • Synchronized with a GaitRite or Zeno mat simply using the 3.5 mm jack connector provided.


Both our EMG receivers are provided FREE of charge with a complete set of APIs that allow the experienced user to integrate the USB acquisition in virtually any software on windows platforms, giving full control of the hardware.

Footswitch FSR sen­sors

Our footswitch sen­sors allow you to cap­ture the con­tact phases of each foot dur­ing the subject’s walk. The kit is com­posed of 8 sen­sors, and can be pur­chased by con­tact­ing your local distributor.

Micro Golden Electrodes

Entirely developed by Cometa, these electrodes are made for small muscles acquisitions, upper limbs, and childres. Coated with a layer of gold, they must be individually gelled and carefully placed, but allow a much higher level of detail, with an acquisition area of only 5 mm in diameter.

WaveTrack elastic bands

These elastic Velcro bands have a small pocket that fits and keeps fixed a WaveTrack transmitter, allowing the use of the sensors in the most dynamic applications, including swimming, running, jumping, etc.

Medical grade stickers

We can provide a full range of stickers, made with 3M medical grade 1622 double sided tape, that allows you to attach to the subject’s skin all of our accessories:

  • Rectangular stickers for EMG transmitters.
  • Round stickers for FSW sensors.
  • Round stickers with hole for our Micro Golden electrodes.


Replacement batteries and lower parts: thanks to the modular architecture of our systems, most of the times it is not necessary to return the whole system to our offices for maintenance. We provide assistance packages for all products from 2005 Zerowire systems up to the most recent WaveTrack. Here is a summary table of what can be done with your system:
