This meeting on "Miniaturization of High Energy Physics Detectors" had two principal aims: on the one hand to offer a Danoramic view, as comprehensive as possible, of this new field whose increasing interest can be understood by means of the justified hope to reach completely unconventional experimental aDparata for high energy physics in a short time: on the other hand to search for sufficient and, if Dossible, more advanced solutions to reduce the present (but more and more the future) gigantic experimental apparatuses to human dimensions. It is the conviction of this Organizing Committee that the first aim has been successfully achieved but for the second one there is still much to do; and so in the near future we foresee a new collective thinking over the progress in this field. Apologising for the delayed publication of these proceedings, due to technical reasons, the Organizing Committee thanks Prof. R. Favilli, Magnifico Rettore of the Pisa University, for his precious contribution to the realisation of the meeting and L. Bulleri, the Mayor of Pisa, for the warm welcome to the participants.
