BioMedical Circuits and Electronics

Circuit: biomedical circuits email: AA
Message: I'm a student in technical studies college, and i need to study medical circuits for my Graduation.

letter from - AA

Look here ...

Biomedical Circuits Technical Committee - The goal of the Biomedical Circuits and Systems (BIOCAS) Technical Committee is to foster research, development, education and industrial dissemination of knowledge relating to the emerging field of microelectronics and nanotechnology in biological and medical applications.

Bioelectric recordings - The instrumentation amplifier circuit normally used in bioelectric recordings is improved for measurements under difficult circumstances. Another application is a low-cost 64 channel amplifier for multichannel ECG recordings. The third application is a device that can be added to bioelectric measurement systems and will provide a major reduction in interference.

Neurostimulation of the spinal cord - The wireless system includes a wearable recording module, a wearable stimulation module and a transceiver connected to a computer for real-time and off-line data processing, display and storage.

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

Mail from JX US


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.
