Scalable Interfacing of Flexible Electronics with High-performance ICs Yingzhe Hu, Warren Rieutort-Louis, Josue Sanz-Robinson, Katherine Song, James C. Sturm, Sigurd Wagner, Naveen Verma Princeton University, Princeton, NJ Abstract Early-stage damage detection for buildings and bridges requires continuously sensing and assessing strain over large surfaces,(More)
With the explosion in the number of battery-powered portable devices, ubiquitous powering stations that exploit energy harvesting can provide an extremely compelling means of charging. We present a system on a flexible sheet that, for the first time, integrates the power electronics using the same thin-film amorphous-silicon (a-Si) technology as that used(More)
Early-stage damage detection for bridges requires continuously sensing strain over large portions of the structure, yet with centimeter-scale resolution. To achieve sensing on such a scale, this work presents a sensing sheet that combines CMOS ICs, for sensor control and readout, with large-area electronics (LAE), for many-channel distributed sensing and(More)
We present a 2nd-generation system for high-resolution structural-health monitoring of bridges and buildings. The system combines large-area electronics (LAE) and CMOS ICs via scalable interfaces based on inductive and capacitive coupling. This enables architectures where the functional strengths of both technologies can be leveraged to enable large-scale(More)
This paper presents an energy-harvesting system consisting of amorphous-silicon (a-Si) solar cells and thinfilm-transistor (TFT) power circuits on plastic. Along with patterned planar inductors, the TFTs realize an LCoscillator that provides power inversion of the DC solarmodule output, enabling a low-cost sheet for inductivelycoupled wireless charging of(More)

Large-area electronics enables the creation of systems with transformational capabilities and form factors. Through the ability to integrate thin-film photovoltaics, batteries, and active transistors, complete power-management subsystems addressing a wide range of applications can also be created. We present, for the first time, a fully flexible system(More)
Capacitive touch screens have enabled compelling interfaces for displays [1]. Three-dimensional (3D) sensing, where user gestures can also be sensed in the out-of-plane dimension to distances of 20 to 30cm, represents new interfacing possibilities that could substantially enrich user experience. The challenge is achieving sensitivity at these distances when(More)
Large-area electronics presents new form factors, enabling ubiquitous systems that are flexible and capable of scaling to very large areas. By processing thinfilm transistors (TFTs) at low temperatures on plastic (using organics, amorphous silicon, metal oxides, etc.), blocks such as ADCs, amplifiers, and processors can be realized [1,2]; however, aside(More)
We report hybrid amorphous (a-Si)/nanocrystalline (nc-Si) Schottky diodes for rectification at high frequencies. All fabrication steps are done at <200 °C, making them compatible with processing on plastic. The diodes have a high current density (5 A/cm2 at 1 V and 100 A/cm2 at 2 V) and ON-to-OFF current ratio (over 1000 for bias voltages of 1/−8 V). A(More)
