[摘要]：Ubiquitous computing is about to become part four everyday lives by integrating hundreds of "invisible" to us computing devices in our environment, so that they can unobtrusively and constantly assist us. This will imply more and smaller "invisible" sensors, homogeneously distributed and at the same time densely packed in host materials, responding to various stimuli and immediately delivering information. In order to reach this aim, the embedded sensors should be integrated within the host material, heading towards sensorial materials. The first step is to omit all parts that are not needed for the sensorial task and to find new solutions for a gentle integration. This is what we call function scale integration. The paper discusses sensor embedding in the human hand as an example of integration in nature, new technological applications and main challenges associated with this approach. (C) 2011 Elsevier B.V.
