The MyoWare® 2.0 Muscle Sensor Basic Kit, an Arduino-compatible, all-in-one electromyography (EMG) sensor kit that provides you with the bare minimum from the MyoWare 2.0 ecosystem to get started measuring and visualizing muscle activity. Simply snap on the MyoWare 2.0 LED Shield, add some EMG sensor pads, attach the sensor to a muscle group, and flex! The kit also includes a mini screwdriver to easily remove shields, USB A to C cable to recharge the 40mAh LiPo battery, and MyoWare 2.0 Reference Cable to connect to large muscle groups.
The MyoWare 2.0 Muscle Sensor included in this kit has been redesigned from the ground up with a new easy-to-use, compact design and upgraded with the latest and greatest chipset improving sensor performance and reliability. The sensor measures muscle activity through the electric potential of the muscle, commonly referred to as surface electromyography (EMG or sEMG for short). When your brain tells your muscle to flex, it sends an electrical signal to your muscle to start recruiting motor units (the bundles of muscle fibers that generate the force behind your muscles).
The harder you flex, the more motor units are recruited to generate greater muscle force. The greater the number of motor units, the more the electrical activity of your muscle increases. MyoWare 2.0 Muscle Sensor will analyze the filtered and rectified electrical activity of a muscle and output a signal (0-VIN volts, where VIN signifies the voltage of the power source) that represents how hard the muscle is being flexed. The innovative snap connector system eliminates the need to solder connections with the MyoWare 2.0 LED Shield. The blue 10-segment bar graph provides a visual representation of the measured signal. The more muscle activation measured, the higher up the board LEDs will go!
This kit is constructed to follow the standalone example featured in the MyoWare 2.0 Muscle Sensor Guide without the need for a microcontroller. Use it to gauge how hard you’re working a muscle during a workout, as a teaching tool, or add some myoelectric flair to your Halloween costume!
Note:
This item may take longer to process due to the battery installed in the equipment and therefore does not qualify for same-day shipping policy.
The MyoWare 2.0 Muscle Sensor and LED Shield are not intended for use in the diagnosis of disease or other conditions, or in the cure, mitigation treatment, or prevention of disease, in a man or other animals.
Includes
1x MyoWare 2.0 Muscle Sensor (Version 2.0.4)
1x MyoWare 2.0 LED Shield
1x Reversible USB A to C Cable - 2m
1x Disposable Surface EMG/ECG/EKG Electrode - 24mm (10 pack)
1x MyoWare 2.0 Reference Cable
1x SparkFun Mini Screwdriver
Note: This kit does NOT include a microcontroller. This is a basic kit to get started with the muscle sensor. Users will need to solder the connection between the muscle sensor and their microcontroller/single board computer using wires or headers. If connecting directly to a single board computer, you will need an ADC and USB isolator.
