Basic EMG Signal Processing

[@jpdieffe]

Some instrumentation amps that I recommend: INA118P or the AD623

[@wastingyourtime1478]

Thank you. I can probably work from the board in the video or do it from scratch now that you’ve proved it works, but a diagram would be a great reference (you don’t need to share it though). Idk how dm’s work. I had a project idea yesterday and I feel like your video is a key step in making the equipment cheaply. I have an arduino and motors to test this with. If my design is the same as yours, I’ll mention your name, but chances are I’ll make something different and use an AI to filter noise, as I have a feeling that the maximum amplitude might be shown by noise (I’ve done no testing yet)

[@qiejdbcjgjfjd6057]

I tried another method to test EMG circuit. I used INA126P(differential amplifier) However, Amplifier does not operate because EMG signal magnitude is very small. Can you comment about this ?? And what is the amplifier you used ?? Please, help ㅠㅠㅠㅠ

[@assignmentable]

this is absolutely amazing! would it be possible to make this device but a lot smaller? around the size of a watch?

[@jpdieffe]

assignmentable anything is possible if you believe.

[@jpdieffe]

If you use smt components it can be tiny

[@muhammadyahya2302]

Can you please share the circuit diagram of this circuit. pretty pleaseeeeeee

[@dugginaren9257]

Can you please circuit send the circuit diagram Which IC did you use for the Bandpass filter and what should be the order of the Bandpass filter (2/3/4)

[@HemangJoshi]

can you please share circuit diagram??

[@skip60cs16]

Could you share the proteus sketch?

[@isacantonacci]

I like the small size of it all, vdry portable! Im thinking about doing a exoskeleton as a senior project, what i was wondering is how much the total cost of the sensors and circuit is? I have a slightly limited budget. I wouod truly appreciate if you could respond! Isac

[@haddadmarcelo]

Very nice work bud. Where did you get those cables? They have a male pin for protoboards?

[@abdelrahmanfarah5877]

Can the circuit be used for EEG?

[@SAMARTHNAIKDHURE_]

No

[@rashiidsherif9222]

For your bandpass filter , what type of active filter did you use? i.e. butterworth , sallen key? What op-amps are you using for filtering? Grat video

[@jpdieffe]

I used a sallen key filter. and I'm pretty sure that the op amps are OPA1013

[@newscientificdiscoveries6228]

What are the sensors? And what are the sensors made of? Is it needle or what?

[@ahmedel.defrawy4968]

could you tell me how to know the proper frequency band width

[@manendrapalsingh6916]

can you provide me with exact circuit diagram

[@SyanthParam]

How do you get rid of lag? I see many projects with people controlling a robotic hand using EMGs and Arduino, but it takes almost a second for the hand to respond to their movements.

[@chrisdonnell7200]

The lag is 90% processing, Arduino Unos and other standard microcontrollers are pretty slow. A simple hardware upgrade will fix the delay.

[@wastingyourtime1478]

I have an ultrasonic distance sensor that has no lag. If the output signal is a value that is fed into the input without processing, there should be next to no lag. I haven’t delved this deep in practice yet. Would the air, clothing or wire distortions change the signal too?@@chrisdonnell7200

[@jsislas6123]

can you share de circuit diagram

[@DevilGTV]

can i get the the values of the resistor and capacitor in parallel with the diode in last stage ...im having problems getting a stable signal

[@AlaaMohammedHanafy]

Please I want the components of the circuit ,their values ​​and connections

[@nfsesl9653]

what instrument did you use?

[@Yorumcu63]

Very nice

[@dugginaren9257]

Hi iam working on the same project but is there a chance to control the fingers using this technique and also, which microcontroller would you prefer.

[@jpdieffe]

I've seen people do this for fingers, you'll have to Google around for electrode placement. Microcontroller depends on your familiarity. I've started really liking the bgm121 from SI Labs.

[@chandramchandram9129]

how can I know that how much voltage is generated. by using multi meter in order to set resistance for opamps

[@jpdieffe]

It's pretty inexpensive, I can't imagine the total cost of components would be greater than $15. I used a MAX1044 so I could run off a single battery (e.g. It gives you +9v and -9v from a +9v supply). If you can afford it, get some OPA1013 op-amps. But any ol' op-amp will work

[@cassiotbatista]

Any chances you could provide the circuit diagram? :)

where you able to drive a motor with this process?

Can we use this circuit with arduino, pls tell

[@Squirrels1999]

I want schematic diagram of this circuit.. plzzzzzz

[@ingmendez4092]

me podrias facilitar un diagrama o una lista de los componentes?

[@ernestojorge4396]

+ing mendez Las partes especificas queda a opinion personal. Google esto: Design And Control of EMG Controlled Prosthetics Limb, lo puedes encontrar en science direct.com. Claro tal vez ya encontraste lo que necesitabas pero por si acaso. Saludos.

[@ingmendez4092]

muchas gracias por tomarte la molestia de contestarme y si lo voy a checar quiero adentrarme mas en este tipo de circuitos

[@Pankiis]

+ing mendez mas que nada utilizo amplificadores operacionales TL082 para el filtro pasa bAja y otro para el pasa alta ambos con ganancia unitaria y al final utilizo otro amplificador operacional pero esta ves de instrumentación en general cualquier circuito integrado INA serviria, y el circuito integrado que toma una fuente de voltaje y y la divide en mas menos el voltaje es un circuito integrado MAX1044

[@ingmendez4092]

Pankiis muchisimas gracias no te imaginas cuanto me has facilitado el circuito

I Used INA106 KP.. High Gain
