Trigno EMG Sensors
Delsys Trigno Wireless EMG Sensors
Range of Trigno EMG sensors from Delsys that are used to measure and wirelessly transmit (≤ 40 m) surface EMG (sEMG) signals to the Trigno Wireless Foundation System and then analyzed in real-time using LabChart software and a Trigno Wireless device enabler.
Overview
The Trigno EMG sensors from Delsys are used to measure and wirelessly transmit (≤ 40 m) surface EMG (sEMG) signals to the Trigno Wireless Foundation System and then analyzed in real-time using LabChart software and a Trigno Wireless device enabler.
Some Delsys EMG sensors also feature a 3 axis accelerometer that can be used for motion studies. All sensors are light weight with signals streamed (≤ 40 m) to the Trigno Base Station (receiver) for freedom of movement.
Sensors are purchased separately to the Wireless Foundation System where the number of sensors is limited to 16 per Trigno Base Station. As a guide, Delsys recommends to include 4, 8 and 16 sensors when appropriate.
Other Trigno sensors are also available:

Product Configurations
Trigno Avanti EMG + IMU Sensor
Provides wireless and flexible measurement of a high fidelity surface EMG signal, with a wide bandwidth 10-850 Hz and 11mV range. Also provides motion detection signals through an onboard IMU (3D Accelerometry, 3D Gyroscope, and 3D Magnetometer). Compatible for use with the Trigno Wireless Foundation System, this lightweight and compact sensor is a multi-purpose human movement sensor for either the lab or the classroom.
Trigno Quattro
The Trigno Avanti Quattro Sensor allows wireless measurement of 4 high fidelity surface EMG signals. It consists of 4 small sensor heads connected via short leads to the main sensor body. A 9 Axis IM sensor is also built into the unit. The sensor is designed to work with the Trigno Base Station (Lab or Digital), which is purchased separately. It can also be used with the Delsys Avanti Android App via a Bluetooth connection. It weighs 25 g, the main body measures 27 x 46 x 13 mm and each of the 4 heads measure 25 x 12 x 7 mm). Note that this is a 4 'slot' sensor which means it counts as 4 sensors towards the 16 sensor limit on each Trigno Base Station.
Trigno Snap-Lead Sensor
Provides wireless measurement of a high fidelity surface EMG signal using clamp style connector leads with Trigno Wireless Foundation System. Each sensor has a built-in IMU. Available with with 4" or 12" Leads.
Trigno Mini Sensor
Provides wireless measurement of a high fidelity surface EMG signal in small and difficult-to-isolate muscles, which is achieved with a small sensing head (25 mm x 12 mm x 7 mm and weighs 2.1 g). It is designed for use with the Trigno Wireless Foundation System. Each sensor has a built-in IMU.
