del Corro, P. G., M. Imboden, D. J. Bishop, and H. Pastoriza. "Comb Drive Designs With Minimized Levitation." Journal of Microelectromechanical Systems 25, no. 6 (2016): 1025–1032.
Abstract: This paper presents two capacitive comb drive
designs for electrostatic actuation of MEMS with the aim to
eliminate the levitation effect often observed in such systems.
By placing a shield over the comb drive fingers, it is possible
to balance the electric field and suppress vertical forces while
maintaining the desired lateral motion. By optimizing the comb
geometry, we demonstrate that our approach is able to reduce the
levitation by an order of magnitude and unwanted coupling of
motion from out-of-plane to in-plane by a factor of 7 compared
with standard comb architectures fabricated using PolyMUMPs
technology, without the need of alternating comb finger polarities
or additional control electrodes. Levitation was reduced to
160 nm, for 3.6-µm lateral displacement at a driving voltage
of 80 V.

"Implementation of an ionizing radiation detector based on a FPGA-controlled COTS CMOS image sensor." In 2017 XVII Workshop on Information Processing and Control (RPIC), 1–6. 2017 XVII Workshop on Information Processing and Control (RPIC)., 2017.
Abstract: This work presents the development and implementation of an ionizing radiation detector based on a commercial off the shelf CMOS image sensor and a FPGA. The response of the system was tested in irradiations with gamma photons, beta and alpha particles using different configurations of the image sensor. Finally, we analyze the possible uses of such configurations in the discrimination of events produced by alpha particles in mixed radiation fields.
