    5. H. C. Ko, et al., Nature 454, 748–753

      They created an hemispherical optoelectronic device that can replicate the functions and characteristics of a human eye such as a wide field of view and low aberrations. This electronic device is based off of single-crystalline silicon and is compressible, which enables the hemispherical shape.

    6. S. Choi, et al., Nat. Nanotechnol. 13, 1048–1056

      Here, biocompatable and stretchable materials were tested for implant use. Gold coated silver nanowires within a polymer were tested to see its conductivity. Using this material they were able to fabricate wearable and implantable soft bioelectronic devices that can be conformally integrated with human skin.

    7. J. A. Rogers, T. Someya, Y. Huang. Science 327, 1603–1607

      They reviewed materials that maintain proper electronic properties while having the ability to be stretched, compressed, twisted, bent, and deformed. They discussed different applications for these technologies and possible commercialization.

    8. T. Sekitani, et al.,Science 326, 1516–1519 (2009)

      They used transistors with a floating gate embedded in hybrid dielectrics at a nanoscale of size, and created a flexible array of these floating gate transistors. They coupled this with a pressure sensitive rubber sheet, and the result was a matrix that was able to read mechanical pressure and store it as an image.

    9. C. Choi, et al., Nat. Commun. 8,

      They test a high density, hemispherical image sensor array comprised of an atomically small MoS2 heterostructure that has the capability of releasing strain. They deem this device to be capable of being a soft retinal implant capable of various imaging elements.

    11. I. R. Minev, et al., Science 347, 159–163 (2015).

      Stiff-neural implants have very rare compatibility with soft-neural tissues. Therefore an soft-neural implant was configured that is elastic like dura matter (the protective membrane of the spinal cord).

    12. Y. M. Song, Yet al., Nature 497

      An elastomeric camera was created in the likeness of ant and beetle eyes. These cameras have close to full hemispherical shapes, at around 160 degrees. This hopes to copy arthropods who have wide-angle field of view, low aberrations, high acuity to motion and an infinite depth of field which are all difficult to replicate.

    15. S. Xu, et al., Science 344, 70–74 (2014).

      They created a thin, comfortable device that can be laminated or stuck to the skin of a person to allow for the monitoring of physiological monitoring for the user. Examples of this could be heart rate or blood pressure. This is also a wireless device.

    16. D. H. Kim, et al., Nat. Mater

      A non-invasive ultra-thin electronic interface was created what is capable of being mounted on tissue using a a protein called fibroin which can be obtained from silk. This protein is capable of being absorbed back into the tissue which results in the mounting of the device. These electronics are capable of neural mapping of the brain.
