||Electronic miniaturization has driven pervasive computing for decades. With the rapid progress of digital manufacturing however, new tools and methods are maturing that enrich the possibilities for ambient and wearable system design. While miniaturized technology remains a key feature, now pervasive system designers work holistically across engineering disciplines. Pervasive systems are getting more affordable because designers can bypass the nonrecurring engineering costs and laborious preparation steps of classic manufacturing, e.g., to create molds or physical templates. Eventually, new classes of pervasive computing systems become feasible: personal devices that are adapted to the preferences and needs of one user, and systems addressing niche applications. The articles in this special issue emphasize the need to develop convenient software tools and accessible process chains, especially for people who are not familiar with manufacturing processes.
