Tactile response is limited for many operations that are preformed in extreme environments due to bulky equipment or the limitations of the human body. In order to allow a user in extreme environments to regain some of their temperature–tactile response, a glove was developed that converts temperature into a vibration felt by the user. An RTD was attached to the glove and connected to a microcontroller. This microcontroller converted temperature into a voltage and transmitted it to a micromotor that controlled the vibration felt by the user. Through this scheme, the user was able to identify a temperature increase with a 4s delay. This paper also presents the system response of the glove to a temperature impulse. Using this system transfer function, it is possible to make improvements to the glove to reduce the overall delay between the glove sensing a temperature and the user recognizing the temperature change.
