In this investigation, we propose a flexible structured illumination microscope (FSIM) to eliminate mechanical moving parts for the phase shifts in the spatial pattern and longitudinal scanning of the specimen. In order to prevent these mechanical motions, we adopt a focus-tunable lens and digital micromirror device (DMD) to replace the lateral motion of the pattern and the scanning of the specimen, respectively, which leads to the enhancement of rapid and precise measurement results for measuring the 3D surface profile of specimens. To realize the proposed system, two types of flexible structured illumination microscopes, Macro and micro types, were constructed and their performances were verified with a plane mirror and step height specimens.

Bedridden patients develop pressure sores, as a result of poor blood circulation and excessive humidity. Conventional bedsore mattresses are designed to vary interface pressure zones, between the body and mattress for improved blood flow. Another approach is to control interface humidity, by forced air circulation. An ideal solution may be interface humidity control, in addition to pressure zone control. In this paper, a thin and flexible structure is suggested for forced air ventilation, that can be placed atop pressure zone controlled mattresses. With fabric covers, drying performances are evaluated for a range of air flow rates.
