Building blocks such as 2-D and 3-D electrical interconnections, hybrid integration techniques and especially modeling procedures (i.e. flexural mechanics and CZM) to optimize multi-layer systems are here described and their insights discussed. These methods can be employed to develop not only RFID smart labels but many other types of flexible smart systems capable of interacting with their environment.enSystems-in-Foil (SiF)Dry film photoresistIsotropic / Anisotropic conductive adhesivesHybrid integrationLow temperatureSi to foilFoil to foilRFID smart labelsPrinted and Flexible electronicsPETthesis::doctoral thesis
