week 8: Construct EMG circuit

Title:

Construct EMG circuit on the breadboard

Objective:


To develop and construct Emg circuit for the project. 


Procedure:

• need to construct the power supply for the circuit. 

• signal acquisition phase for EMG sensor

• signal conditioning which for amplification and rectification the signal 

• the complete circuit for EMG circuit on breadboard 

Result:

fully construct the Emg circuit on the breadboard and ready to tested in the laboratory 




Conclusion


 to construct  and develop the circuit, there have e few step that need to follow. the arrangement of component need to be construct acccording to the schematic diagram for getting the correct output.   

mid term break: find the alternative solution for replace component emg lead wire

Title:


 Find the alternative solution for replace component emg lead wire




Objective:


 To find the suitable component that can replace emg lead wire




Procedure: 

• firstly, i do research find the component that has same function with EMG lead wire
• this research has been done because of the difficulty to find the lead wire.
• the component must suitable and can connect with the electrode.

Result:

• according to the definition by http://www.merriam-webster.com/dictionary/alligator%20clip which a spring-loaded clip that has jaws resembling an alligator and is used for making temporary electrical connection. the illustration for alligator clip.

• Before this, there have a few test for measure the EMG using alligator clips and the result  getting from that test is success. The output produce is the same result with using Lead wire.

Conclusion:

I can concluded that alligator clips can be used for replacing the Lead wire according to the previous experiment which using alligator cable to connect the electrode with the circuit. Alligator clips can be used for  transferring the signal that has been pick up by the electrode to the circuit and the micro controller can store that data before process it.  

week 7: order differential amplifier

Title:

 Order differential component

Objective:


To get the component from the element 14 company. 

Procedure:

1. Print out the list of component that i needed from the element 14 website. 
2. Get help from my supervisor to order it because i do not have Maybank account and credit card.

Result:


My supervisor, Mr Syazwan have agreed to buy it from element 14 website. 


Conclusion:


I just need to wait the component arrived within3 day in working hour

week 6: finding research about the component

title:

finding research about the component to develop the EMG sensor circuit

objective:

to get the feedback from the supplier about the component needed.

procedure:

1. contact   AD INSTRUMENT company representatives through the phone and asking about the price for the selected item . http://www.adinstruments.com/contactus/offices/asia/
2. contact a Premier Farnell company that sell the component INA 106KP IC which precision fixed gain differential amplifier through email.

result: 

1.  item lead wires and disposable electrodes is still produced by   AD INSTRUMENT   company but they  need the customer purchase more than 100 item because they did not accept in small quantity.
2. the time delivery for the customer to received the item also take time almost 1 month.
3. the feedback from the Premier Farnell company is can buy online the component and only can use the maybank2u for purchase the component.

conclusion:

the outcome achieve the objective because supplier for the selected item has give the feedback. the AD INSTRUMENT representative  give other solution for get the item in less time which suggest went to the store that sell the medical device such as at subang medical centre. 

week 5: research about the component

title:

research about the component to develop the EMG sensor circuit

objective:

to get the suitable component for design and develop the EMG sensor circuit

procedure:

1. first research about the company that sell the medical equipment and all the accessories for electromyogram device.
2. the component needed is the accessories for EMG such as lead wires and disposable electrode.
3. second research about the company that sell the component INA 106KP IC which precision fixed gain differential amplifier.

result: 

1. the company that sell the accesories for electromyogram device is http://www.adinstruments.com/products/hardware/education/Transducers*and*Accessories/Biopotential*-*ECG**EMG**EEG/

Lead Wires

Disposable Electrodes 

1. the company that sell the component INA 106KP IC is http://store.aztronics.com/index.php?route=product/product&product_id=63

2. 

   INA106KP - PRECISION FIXED-GAIN DIFFERENTIAL AMPLIFIER

3. the lead wires and diposable electrodes needed to order first but the company website do not give the price so need to contact the company first before can order the device.
4. the component for INA 106KP ic also needed to order. 

conclusion:

the outcome did not achieve the objective because the component needed is currently unavailable and need get the feedback first from the supplier before can start develop the circuit. 

week 4: continue find the EMG signal

title: 
continue find the emg signal


objective:
to get the qualified signal electomyogram (EMG)


procedure:

1. enter the laboratory on 9 February 2012
2. repeat the same procedure as last week experiment

result:
the outcome waveform is equal with the result before this..


conclusion: 
the outcome has achieved the objective. the suitable signal was produce. 

week 3:Step 1 on how to get the EMG signal

Title: 


Step 1 on how to get the EMG signal

Objective:

To get the electromyograph (EMG) signal


Procedure:

1. booking laboratory for start the experiment for getting the EMG signal.
2. 3 feb 2011 at 10 am untill 12 pm, start the experiment Emg with guide from supervisor Mr. Mohd Syazwan Md. Yid.
3. by referring to the experiment EMG which getting the signal from the hand..

Result:


the result get is as the expected result from that experiment.this is the video for the EMG signal from the hand.

Conclusion:


as a conclusion, the experiment is success and now i know how to conduct the experiment and after this need to conduct the experiment EMG but must getting the signal from the shoulder, not from the hand.
