The errors in reproduction may indicate some unaccounted factors in the transfer characteristic of EET-polygraph system. Euture work on EET will include identification of these transfer characteristics. Overall, the proposed tester of physiological sensors proved to be an accurate and repeatable device capable of polygraph sensor testing. 

An electronic and electromechanical tester of physiological sensors was implemented to provide direct actuation to the polygraph sensors that are placed on humans during data acquisition and in this way simulate physical manifestations of physiological... 

In contrast, Simpson (1974) advocated augmented cable control. He coined the phrase extended physiological proprioception (EPP) to indicate that the body s own natural physiological sensors are used to relate the state of the prosthetic arm to the operator. EPP can be thought of as the extension of one s proprioceptive feedback into an intimately linked inanimate object. Consider a tennis player hitting a ball with a tennis racquet. The player does not need to visually monitor the head of the racquet to know where it will strike the ball. Through experience, the tennis player knows how heavy and how long the tennis racquet is. He or she knows where in space the head of... 

Conductive tape (Courtesy of Bally Ribbon Mills) is used to neutralize the static electricity and EMI shielding. An elastic webbing (Courtesy of Bally Ribbon Mills) with cable has been used for undersea communication. Physiological sensors and other sensors have been incorporated into textile substrate to monitor heart rate, skin temperature, movement and respiration, and muscle activity for medical and sports applications. RIP (respiratory inductance plethysmography) belts (Courtesy of Natus Neurology Incorporated) are used for sleep apnea monitoring. A conductive belt is used to make electrodes for EEC and other medical applications. A 3D conductive webbing (Courtesy of Bally Ribbon Mills) is also used as ON and OFF switch. 

Initially, and from a purely technical point of view, the smart textile concept may be perceived as the result of a convergence between two industries textiles and electronics. The miniaturization of electronics makes it possible for people to carry with them all kinds of devices, qualified as portables , that have functions ranging from leisure (Walkman, MP3, portable television) to communication and information management (mobile phones, personal digital assistants) to health (pacemakers, physiological sensors of parameters). 

Physiological sensors mainly used for biomedical measurement are surface electrodes, pressure sensors, thermistors, and photodiodes. A surface electrode is a transducer that coverts ionic current in the body to electrical current [13]. Medical surface electrodes are placed in contact with skin of the subject to monitor biopotential generated by tissues and organs. The biopotential originated from the electrical brain...
