| Research Abstract |
To clarify the motor function of the infant tongue during sucking, we developed an artificial nipple that contained multiple small built-in force sensors integrated with a PC-based system which is capable of measuring tongue-artificial nipple contact pressures in real-time. The results from each force sensor showed a pressure waveform of a nearly simple harmonic motion that indicates peristalsis-like movement of the tongue; sucking frequency was about two times per second. In addition, in the low birth weight infant, the pressure changed as the infant grew.
