Vanderbilt researchers have developed a novel method for contactless simulation of the central nervous system. This technique involves the use of infrared neural stimulation (INS) to evoke the observable action potentials from neurons of the central nervous system. While infrared neural stimulation of the peripheral nervous system was accomplished almost a decade ago, this is the first technique for infrared stimulation of the central nervous system.
A Vanderbilt engineering senior design team has developed a car seat safety attachment that detects if a child has been left unattended in a car seat and if the environment has become uncomfortably hot or cold. The system is designed with a graduated alarm system based on "alert states" that provides a combination of visual, tactile and audio alerts.
