2. Bluetooth
The wireless EMG sensor, connects to paired devices via low-energy Bluetooth to enable da ta transmission. The wireless EMG sensor, needs to enter pairing mode before connecting to a new devic e, in order to pair the low-energy Bluetooth with the device. In pairing mode, the wireless EMG sensor’s low-energy Bluetooth continuously broadcasts signal s, Waiting for new paired devices, to detect the signals and then initiate pairing and subscription. he s ame group of Bluetooth devices only needs to be paired once .The optimal number of de vice pairings is up to 4, which ensures the most stable signal transmission. The more pairi ngs there are, the more delayed the data transmission becomes

In the off state of the device, press and hold the button for about three seconds. When the device vibrates once, release the button to turn on the device.
In standby mode without a Bluetooth connection, the blue indicator light will flash once every 3 seconds.
Streaming mode
In standby mode, when the equipped device connects to a Bluetooth device, it will vibrate continuously for 1 second.
The blue indicator light flashes once every second, indicating that the device is in streaming mode after being connected via Bluetooth.
Indicator light is flashing.
Indicator light stays continuously lit.
3. Installation and Wearing
When using the wireless EMG sensor, the two electrodes need to make direct contact with the skin surface, and be secured above the muscle to be tested. We usually need to u
se doublesided tape to attach the sensor to the skin surface, or use straps to secure the sensor to the user’s limb.
3 / 11
Figure 1 LFix the Sensor Using Double-sided Tape RUse Strap to Secure the Sensor
Use Scenario 1 When the space around the target muscle is limited and it is not possible to directly attach the wireless EMG sensor to the skin, you can use an electrode extension cable to secure the wireless sensor at a closer position. To minimize the impact on hand gripping activities, thinner and smaller electrodes can be applied to the palm. Use Scenario 2 You can also mount the wireless EMG sensor on the dorsum of the shoe and secure it with the shoelaces. Subsequently, an electrode extension cable can be used to extend the electrode to the skin surface over the tibia in the anterior lower leg, allowing for the measurement of the tibialis anterior muscle that controls dorsiflexion of the foot . Precautions When the electrode extension line is connected to the sensor, the electrodes at the bottom of the sensor will become inactive, so these two types of electrodes cannot be used simultaneously. Only the electrodes on the connected extension line can collect surface electromyography signals.
Figure 2
Figure 3
By using electrode extension lines, the sensor can be placed on the limb, thereby reducing interference and restriction on limb movement.
You can secure the sensor to the shoe using shoelaces, and then use electrode extension wires to measure the muscle electrical activity in other parts of the body.
Note: The electrode extension wires require two additional disposable electrode pads, which can be secured to the electrode port at the end of the extension wire using a button form. Disposable electrode pads are consumables and can be purchased separately from the distributor if needed.
4. Charging
The wireless EMG sensor is equipped with a USB Type-C charging port. Please use USB

6. Data collection mode
After successfully connecting the Bluetooth device, you can press “Next” to enter the EMG. measurement page. On this page, the mobile software will continuously monitor and display the changes
in the target EMG, signal in real time, as well as display the current root mean square (RMS), value of the EMG, signal in real time. You can press a button to toggle, the display of the surface electromyography (sEMG). signals. In th e signal chart, the sEMG will be represented by a blue line. You can press a button to toggle, the display of the root mean square (RMS), of the surface electromyography (sEMG), signals. In the signal chart, the RMS, will be represented by a red line. T he root mean square (RMS), of surface EMG signals is defined as calculating the average of the s quared values. of a set of surface EMG signals, and then taking the square root of that average. The root mean square (RMS), results in a smooth linear envelope used to estimate the average ampl itude of signals composed of positive and negative oscillations. As shown in Figure 4, the red ro ot mean square curve illustrates the variation of the measured, surface electromyography signal’s effective value. The following is the calculation formula for the root mean square (RMS) of electromyography signals.
