Stretchable Electronics: Materials Strategies and Devices

“…[25] Similar layouts, in interesting but nonfunctional demonstrations, can be achieved using cantilever-sprinas that interconnect silicon islands. [27][28] …”

“…Here, open meshes [6] constructed in bendable materials provide large, reversible levels of deformability for strains applied along certain axes, for systems such as sensitive robotic skins. [27] Cantilever-spring structures in silicon exploit a related physics. [27,28] In this paper, we review these strategies, provide examples of device level demonstrations of them and conclude with some perspectives on future research opportunities.…”

Characterization of Charge Collection in Photodiodes under Mechanical Strain: Comparison between Organic Bulk Heterojunction and Amorphous Silicon

“…

An important application of mechanically flexible electronics is photodiodes for photovoltaics [1,2] and photodetectors, [3,4] because the ability to conform to curved surfaces can simplify optical systems. [5,6] For example, bending planar devices into a hemispherical sensor array will enable applications that require a wide-angle field of view. [7,8] Due to the growing interests in flexible electronics, the strain-induced changes in electrical properties of thin-film transistors have been characterized for both inorganic amorphous silicon (a-Si:H) [9][10][11] and organic materials, [12] but the effects of mechanical strain on photodiodes have been reported only for thin-film a-Si:H. [13] To achieve low-cost photodiodes that are easily scalable to large areas, good alternatives to a-Si:H are organic semiconductors which have the advantage of higher strain tolerance than brittle inorganic materials.

Responsive Hydrogels Based Lens Structure with Configurable Focal Length for Intraocular Lens (IOLs) Application

“…Such stimuli induced geometrical change will result in strong nonplanar imaging capability and autonomous control. [16][17][18] Recent study by Dong and co-workers [19] presented a hydrogel based adaptive liquid lens, where the water-oil interfaces were pinned and deformed by actuating ringshaped hydrogel structures by changing temperature and pH, mimicking the mechanism of a human eye. The utilisation of responsive materials could simplify the lens design without degrading the field of view, focal area, illumination uniformity, or image quality.…”
