de Wit, J.J.M. (author), van Rossum, W.L. (author)A sensor network has been developed consisting of four RF nodes that automatically set up a network organization and synchronize wirelessly. In the system bistatic backscatter and forward scatter radar measurements are combined. For detection of small and slow targets, like humans, suppression of the background including the direct signals...conference paper 2018

(author)Split-gate ambipolar organic transistor technology is gaining interests as a practical solution for the implementation of complementary transistors. It is known that conventional ambipolar transistors suffer from poor DC gain, noise margin, and high power consumption, as they do not have a well-defined off-state region.
