Abstract
In this paper, the development and design of a new prototype of the 18-month-old dummy (the TNO P1 1/2) are presented, and the rationale behind its design is discussed. Based on regulatory and research applications of the P1 1/2, performance specifications are set up. The most important specifications concern the anthropometry and biofidelity of the new dummy. In addition, other characteristics (repeatability, reproducibility, durability, etcetera) have been taken into account during the design process. Using the latest anthropometry data available, incorporating enhanced instrumentation and applying new materials to improve biofidelity, have provided an advanced child dummy design. (A)
