Electronic power systems follow the general trend of miniaturization and functional density. 3D technologies provide an interesting response if adapted to power specifications. In the framework of the ENIAC JU funded project Enhanced Power Pilot Line (EPPL), a new type of device has been proposed consisting of an H bridge of power transistors and a Si interposer. This paper presents an H bridge of...
Organic Large Area Electronics (OLAE) has been identified as a key enabling technology for smart sensing. Moreover, printed electronics brings the flexibility to fulfill these applications. In this paper, the last major results on different printed interfacing Organic Thin Film Transistors (OTFTs) circuits and sensors are presented. An OTFT addressing matrix and organic photodiodes (OPDs) have been...
Screen-printed piezoelectric flexible microgenerators are presented. The features of this work are the deposition of multilayers of P(VDF-TrFE) thin films and organic electrode of PEDOT:PSS. Dielectric, ferroelectric and direct piezoelectric constants are reported as a function of film thickness. Direct voltage coefficient g31, measured for the first time, is shown to reach 0.118 V.m/N. In open-circuit...
Fabrication and characterization of multilayered screenprinted P(VDF-TrFE) piezoelectric microgenerators is reported. Micrometer-sized films were deposited on a flexible polymer substrate with evaporated gold-bottom electrodes, followed by deposition of PEDOT:PSS electrodes. Electrical characterization showed excellent ferroelectric properties and open-circuit voltage was measured as a function of...
Large area sensing surface have strong interest for many applicative sectors: transport, health, building, industrial, user interface… Printed electronics offers breakthrough technical solutions to fulfill these applications. Indeed printed sensors, addressed by printed oTFT matrix and circuits, heterogeneously connected to classical Silicon microprocessor for the signal processing, offers unreached...
