Project Status

Two masks for corn snakes and two masks for bearded dragons have been tested and delivered. Excellent data, closely matching that found in literature, has been obtained using the snake mask. The animal that we tested the bearded dragon mask on was not calm enough for acquisition of data matching that of literature, but breathing was detected, with a signal to noise ratio of approximately 5. A new design for the bearded dragon face mask has been suggested, but will not be built this semester.
