This paper presents the design and implementation of an advanced system on flexible and stretchable technology. The technology platform consists of a matrix of flexible non-stretchable functional islands linked together by a net of elastic interconnections. Several technologies have been developed and tested in the design of simplified demonstrators before studying the design of an advanced system. The target system is a wireless battery charger which supplies power and supports bidirectional data transfer during recharge. The system is intended to serve as a general purpose platform for biomedical parameter monitoring and the design is focused on the embedding in clothes.
This paper introduces a novel and simple topology for an efficient, miniaturized, low power but high data rate transmitter, suitable for implanted devices. The application envisaged is in capsular endoscopy, where high quality images of the gastro-intestinal tract need to be transmitted continuously through the human body to an external receiver. A 2 Mbps Frequency Shift Keying transmitter is developed, consuming 2 mW at 1.8 V, working at biocompatible frequencies.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
