Secret communication device
Spying activities should be confidential, and need smooth communication. In films, agents carry out missions while receiving instructions continuously. So I thought that the agent should can communicate with control center even in emergency or in the situation of can't using their both hands. For these, I thought communication device that could be attached to inside the upper teeth. Agent can send Morse code using tongue, and the feedback is transmitted from the mouth ceiling to agent using bone conduction technology. All the process of sending and receiving messages is done invisibly and secretly, and there is no danger of overheard.
Thanks to allow me to share this honor. To be better and better, I'll believe myself and do my best. Thanks IF Award!UNIVERSITY
