What is it?

A candy-size single-channel ElectroMyography (EMG) sensor for precise recording of muscle signals at an affordable cost. It is an SMD version of Muscle BioAmp BisCute that can be used to make amazing Human-Computer Interface (HCI) projects.

What is Electromyography (EMG)?

Electromyography (EMG) is a technique for evaluating and recording the electrical activity produced by skeletal muscles.

Electromyography is used in various real-world applications like,

• Prosthetic hands,
• Human augmentation,
• Games controllers,
• Rehabilitation and
• Physical therapy to name just a few.

Even doctors are using them for the diagnosis of various neuromuscular ailments.

Recently, It was in the news that Meta is working on wearable EMG sensors to track user movements in the metaverse.

The image below shows an EMG signal recorded with Muscle BioAmp Candy.

Connecting with Arduino and BioAmp Cable:

To get started, you can pair Muscle BioAmp Candy with any development board with an ADC (Arduino UNO & Nano, Espressif ESP32, Adafruit QtPy, STM32 Blue Pill, BeagleBone Black, Raspberry Pi Pico, to name just a few) or any standalone ADC of your choice.

To measure the EMG signals, connect either BioAmp Cable v2 or BioAmp Cable v3 with your muscle sensor as shown in the images below:

CAUTION: Make sure to follow the above diagram while making the connections between your Muscle BioAmp BisCute & Arduino (or any other ADC of your choice), especially the GND and VCC else it may damage the muscle sensor.

What is included in the Kit?

• Muscle BioAmp Candy
• Free BioAmp Accessories Kit (3 Gel Electrodes, BioAmp Cable v2 (50cm), Muscle BioAmp Band, 3 Jumper Cables)

Note:

• Gel electrodes should only be used once, and discarded afterward – treat them like sterile medical products!
• Muscle BioAmp BisCute comes with 3 electrodes but you can easily buy them from here.
• BioAmp Accessories Kit is free till the stock last.

Why did we make Muscle BioAmp Candy?

EMG devices are typically quite expensive, as they are medical-grade diagnostic devices. But with an affordable EMG sensor like this, you can record biopotential signals from muscles, conduct experiments and make amazing projects at a fraction of the cost of a professional EMG machine.

We want to make neuroscience affordable and accessible to all so that students and researchers get inclined towards neuroscience and explore it by doing awesome projects at ease.
