Assignment#1 Survey on sensors and actuatorsSlide-3IntroductionNeural sensors are sensors designed to pick up the bio-electric signals that the brain and nervous system of all living creatures produce. There are a number of different ways to detect these signals and a number of techniques for interpreting what is detected. Most of the applications are still experimental but the potential for these sensors is limitless.01/16/19ECE5320 Mechatronics.

Assignment#1 Survey on sensors and actuatorsSlide-7Obstacle 1: Signal DetectionThere are two major obstacles to overcome in making useful measurements of the neural system. The first obstacle is detecting the signals. These signals are usually only a few millivolts in amplitude and must be measured through the non-homogenous medium of the human body. A number of different techniques have been invented to make these measurements.01/16/19ECE5320 Mechatronics.

Assignment#1 Survey on sensors and actuatorsSlide-9Measurement Classifications•galvanic skin response (GSR)-This test measures the resistance of the skin to a small current passed though it. The resistance of the skin will change depending on the mood and emotional reaction of the subject•electroencephalogram (EEG) – The measurement of electrical activity in the brain usually through electrodes or a type of skullcap•electromyelogram (EMG) – The measurement of electrical activity in muscles. Usually measured through needles inserted into the muscles. •electrocardiogram (ECG/EKG) – The measurement of electrical activity in the heart•silent speech detection – A specialized type of EMG. Small sensors are placed on the throat to detect the neural impulses made by speaking or thinking about speaking.•cognitive engineering – An experimental advance on EEG, this techniques uses electrodes implanted directly in the brain to read brain electrical activity.01/16/19ECE5320 Mechatronics. Assignment#1 Survey on sensors and actuatorsSlide-10GSR: Principles and ApplicationsA sensor pad is placed on the subject, usually the finger and the conductivity of the skin is measured. The resistance of the skin will change according to the mental state of the subject. Shock, stress, surprise, and general mood will affect the resistance of the skin.GSR has been used in tests on anxiety and stress, in biofeedback therapy, and sometimes as a lie detector. Some research is being done in using GSR sensors to help with athlete mental
