2.  Problem Statement ◦ Develop a handheld device, that with minimal specialized training, can be used to quickly record EEG signals in the field.

3.  Handheld device with two Ag/AgCl cup electrodes with pins to penetrate hair  “D” clip electrode leads

4. Patient has a medical emergency First responder determines if they are able to undergo a field EEG YES Once the patient arrives at the hospital, the data is transferred to the diagnosing physician Patient is taken to hospital for care Field EEG is performed on the patient for all available reading locations NO

5.  Quickly record accurate EEG signals  Require limited training and experience to operate  Store signal results for later analysis  Record placement of each individual recording  Visual feedback for a good connection  Pivoting electrode housings

6.  Next Step to test electrodes in the handle assembly.

7.  Tested Electrodes and leads on the Gtec biosignal acquisition system and Texas Instrument Performance Demonstrator  Recorded 4 wave forms: ◦ Eyes open ◦ Eyes closed (Alpha) ◦ Eye blinks ◦ Jaw clench

8.  Eyes Open  Eyes Closed

9.  Eye blink  Jaw Clench

10.  Jan 7 th - Have plan and parts ordered for pivoting Electrodes  Jan 14 th - Finalize plan for marking EEG recording location  February 1 st - Have final prototype built (ideally with signal amplification built in to the handle)  February 15 th -Complete any necessary Testing  February 28 th - Finalize any open paperwork
