Years of Research and Development:
Robust Dry Electrode sEMG Sensor

As a result of great efforts, our long lasting "Dry Electrode sEMG Sensor" development have been completed. With our great experimental results we are able to introduce you with our sEMG sensor which are suitable for medical grade bionic hands.

World Class sEMG Sensor

R&D is Challenging
We've Done It For You

Numerous large technology giants and small businesses are developing "Bionic Hand Prosthesis", although research and development is a time-consuming task. The most challenging part is to design a robust dry electrode sEMG sensor. The good news is that we've done it for you, and it will be completely open sourced.

Dry Electrodes is a Must
Practical Use

The bionic hands that developed with wet electrodes are difficult to install and remove, making patients' lives difficult. Therefore dry electrodes are prefered in major prosthesis companies's designs. Despite difficulties at development stage , it has become a necessity to develop an active dry electrode design that mimics the same wet electrodes since more confortable for sufferers.

Final Status of
sEMG Project

Our team consists of engineers specialized in different disciplines. As a team, we are aware of how important it is to minimize the problems experienced by prosthetic bionic hand developing companies and to make people's lives easier. Our project, which we have developed with great devotion in this process, is finally being finished. While optimizations in the main parts of analog electronics and digital electronics continue, improvements in mechanical design and mass production are in progress.

World Class sEMG Sensor

Embedded AFE
High CMRR/SNR

sEMG sensor contains highly optimized Analog Front End (AFE) for a high signal noise ratio. AFE is made of simply a differential amplifier, a RLD circuit and various analog filters which ensures high CMRR and SNR's. The signal conditioner circuit is integrated and the absence of analogue cables out of the sensor provides a clean signal.

Digital Output
Read from Digital Bus

Our sensor also contains a Cortex M4 MCU with DSP capabilities in order to improve SNR even better with various digital FIR filters. MCU also computes RMS of the filtered and amplified signal. Processed RMS values is smoothed via a smoothing filter and MCU writes the values to the I2C or UART bus.

Dry Electrodes
Strangly Robust

Thanks to our dry electrode sEMG sensor that can be fixed on the prosthesis socket and can work directly without gel, your bionic hand projects will be incredibly practical.
Patients using bionic hand prostheses developed with our sensors will be able to wear and remove prostheses as a glove thanks to the practicality of dry electrodes.

World Class sEMG Sensor

All In One Complete Solution
AFE + ADC + DSP

It is very easy to use the sensor in bionic hand projects. All you have to do is to read the RMS sEMG values from the sensor via the UART. With these values sent by the sensor, you can develop bionic prosthetic hands that can provide a very precise, proportional force information so that you can keep an egg without breaking it.
All calibration settings of the sensor are also carried out via the UART data line.

Medical Compatibility
Safe to Use

We used TiN (Titanium nitride) as an electrode coating material owing to its biocompatibility and chemical stability. It is designed to limit the current always less than 5 μA even in fault conditions and for compliance with medical standards in many areas such as “IEC 60601-1”
