We present FlexSense, a new thin-film, transparent sensing surface based on printed piezoelectric sensors, which can reconstruct complex deformations without the need for any external sensing, such as cameras. FlexSense provides a fully self-contained setup which improves mobility and is not affected from occlusions. Using only a sparse set of sensors,(More)

Ferroelectric material supports both pyro- and piezoelectric effects that can be used for sensing pressures on large, bended surfaces. We present PyzoFlex, a pressure-sensing input device that is based on a ferroelectric material. It is constructed with a sandwich structure of four layers that can be printed easily on any material. We use this material in(More)
The performance of organic thin-film transistors (OTFT) for flexible, low cost and disposable “plastic” electronic products advances rapidly: various organic semiconductors display hole or electron carrier mobilities that compare favorably with those of hydrogenated amorphous silicon, the inorganic counterpart for such applications as flexible displays,(More)
FlexCase is a novel flip cover for smartphones, which brings flexible input and output capabilities to existing mobile phones. It combines an e-paper display with a pressure- and bend-sensitive input sensor to augment the capabilities of a phone. Due to the form factor, FlexCase can be easily transformed into several different configurations, each with(More)
Ferroelectric material supports both pyroand piezoelectric effects that can be used for sensing pressures on large, bended surfaces. We present PyzoFlex®, a pressure-sensing input device that is based on a ferroelectric material (PVDF:TrFE). It is constructed by a sandwich structure of four layers that can easily be printed on any substrate. The PyzoFlex®(More)
