Photonics for a Better World

The future happens at SPIE Optics + Photonics What will the future look like? For technologists, policy makers, and venture capitalists alike this is the million-dollar — really billion-dollar — question. For scientists and engineers working on the technology that will fuel this future, the question is more about where to secure funding, where to publish, and where to present their research. SPIE’s Optics + Photonics symposium in San Diego this August is the choice of many of these top researchers to present their latest iterations on future-impacting technology. The future of medicine Technology will most certainly play a large role in the future of healthcare, from innovative imaging techniques and personalized medicine to further understanding of the brain and how it functions and malfunctions. While not a major focus of the symposium, many healthcare-enabling technologies will be presented. A group of Italian researchers will be presenting their work utilizi...

Wearables including temporary tattoos are contributing to a paradigm shift in healthcare monitoring; above, a slide from a presentation by Nanshu Lu on graphene electronic tattoos for monitoring organ function. Wearable devices, materials, and even temporary tattoos are entering healthcare and other markets, offering the potential for faster, more accurate, and potentially life-saving treatment. Tracking and measuring activity in the 11 major organ systems in the human body systems is imperative for medical providers to quickly and accurately diagnose and treat patients experience trauma or other emergencies. But existing medical equipment may be uncomfortably bulky or take valuable time to set up. Skin-like devices and other technologies can provide unobtrusive, comfortable, and precise alternatives for sensing what is happening inside the body. In one development, researchers at the University of Texas at Austin are developing a skin-like temporary tattoo that ta...

Ultraviolet image from NASA’s Galaxy Evolution Explorer shows NGC 3242, a planetary nebula frequently referred to as “Jupiter’s Ghost.” Image courtesy NASA/JPL-Caltech Are there any connections between space technologies and healthcare? You bet there is, says Shouleh Nikzad, senior research scientist at NASA’s Jet Propulsion Laboratory (JPL) at the California Institute of Technology (Caltech) and the principal engineer, co-lead, and technical director for JPL’s Medical Engineering Forum. Numerous optics and photonics technologies originally developed for space applications have found their way into consumer and medical markets, Nikzad writes in the April 2017 issue of SPIE Professional magazine . Infrared thermometers, workout machines, compact cameras in mobile phones, and imaging technologies are just a few familiar examples. Ultraviolet imaging is also used in medical applications to reveal disease, as in this image of cancerous brain tissue. ...
