Bioamp for muscle signals - EMG

message: I'm working an a bioamp for muscle signals. This is the base design, but it does not work. Basically what I want to do is a circuit that amplifies my muscle signals and is able to run a small dc motor when I flex a muscle. Any help? Thanks

Electromyography (EMG)  - An electromyograph detects the electric potential generated by muscle cells. when these cells are electrically or neurologically activated.

Electromyography EMG

Study these links and send me a feedback ....

Positive Feedback Circuit for Isometric Muscle Experiments - he part of which I am most proud is the innovative Automatic Gain Control (AGC) circuit, without which the project would not have succeeded. This AGC circuit could well be used in many other applications too

EMG design parameters - The device must be able to detect the small signals arising from muscular contraction and amplify them without also amplifying ambient noise which may exist in the recording environment and which is likely to be of approximately the same magnitude as the signals of interest.

Important Factors in Surface EMG Measurement - Small electrical currents are generated by muscle fibres prior to the production of muscle force. These currents are generated by the exchange of ions across muscle fibre membranes, a part of the signaling process for the muscle fibres to contract. The signal called the electromyogram (EMG) can be measured by applying conductive elements or
electrodes to the skin surface, or invasively within the muscle

ECG EEG EMG bio-amplifier

i need to build a bio-amplifier capable of amplifying ecg, eeg & emg signals and displaying the corresponding waveforms on a computer monitor. the bio-amp has to be accompanied by a software program built using QBasic/QuickBasic. the bio-amp must use an rs232 serial interface port. is it possible for delabs to undertake this project. please reply asap. thanx.
