HELPING PIKE COUNTY TAXPAYERS MY GOAL IS SIMPLE RECORDER Lida Robinson H H ELECTH H Paid For By Lida Robinson For Recorder What if we could hear gravity and what does it tell us about space-time? The 2017 Nobel Prize winner in physics will dis- cuss "What if we could hear gravity? " as part of an Oct. 17 Ideas Festival event at Purdue University. Experimental physicist Barry Barish will present "What if We Could Hear Gravity: The Detection of Gravitational Waves from Colliding Black Holes," at 7 p.m. at Stewart Center's Loeb Playhouse. Experimental physicist Barry Barish, a 2017 No- bel Prize winner, will pres- ent "What if We Could Hear Gravity: The Detection of Gravitational Waves from Colliding Black Holes," at 7 p.m. Oct. 17 at Stewart Cen- ter's Loeb Playhouse. Bar- ish's presentation is aligned with Purdue's Giant Leaps Sesquicentennial Campaign and is part of the Ideas Fes- tival theme, Giant Leaps in Space: Earth, Exploration, Economics. The Ideas Fes- tival is the centerpiece of the campaign and connects world-renowned speakers and Purdue expertise in a conversation on the most critical problems and op- portunities facing the world. On Sept. 14, 2015, gravita- tional waves were observed for the very first time. The waves, which were predicted by Albert Einstein 100 years ago, came from a collision between two black holes. It took 1.3 billion years for the waves to arrive at the Laser Interferometer Gravitation- al-Wave Observatory detec- tors in the United States. LI- GO is a collaborative proj- ect with more than 1,000 re- searchers from more than 20 countries, and Barish was the lead principal investiga- tor. Together, the research- ers realized a vision that is almost 50 years old. "Gravitational waves are direct testimony to disrup- tions in space-time itself," said David Koltick, Purdue professor of physics and as- tronomy. "This is something completely new and dif- ferent, opening up unseen worlds. A wealth of discov- eries awaits those who suc- ceed in capturing the waves and interpreting their mes- sage." There will be a reception starting at 6 p.m. for Barish, who is the Linde Professor of Physics Emeritus at Cal- ifornia Institute of Technol- ogy, before the Oct. 17 lec- ture in the Robert L. Ringel Gallery, also in the Stewart Center. He also will give a more technical lecture as the Hubert M. James Me- morial Lecture, on Oct. 18 at 4:30 p.m., in Room 114 of the Physics Building. Two black holes merge into one. The collision of two black holes holes—a tremendously powerful event detected for the first time ever by the Laser In- terferometer Gravitational-Wave Observatory, or LIGO—is seen in this still from a computer simulation.

Having to continuously monitor your status without a doctor when you are back home can be even scarier. Imagine being able to do that with a simple sticker applied to your body. Purdue University re- searchers have advanced a sticker solution moving it several steps closer to re- ality. The research was re- cently published in ACS Ad- vanced Materials and Inter- faces. A YouTube video is available at http://bit.ly/ EPED-Purdue. "For the first time, we have created wearable elec- tronic devices that some- one can easily attach to their skin and are made out of pa- per to lower the cost of per- sonalized medicine," said Ramses Martinez, a Purdue assistant professor of indus- trial engineering and bio- medical engineering, who led the research team. Their technology aligns with Purdue's Giant Leaps celebration, acknowledging the university's global ad- vancements made in health as part of Purdue's 150th an- niversary. This is one of the four themes of the yearlong celebration's Ideas Festival, designed to showcase Pur- due as an intellectual cen- ter solving real-world issues. The "smart stickers" are made of cellulose, which is both biocompatible and breathable. They can be used to monitor physical activity and alert a wearer about pos- sible health risks in real time. Health professionals could use the Purdue stick- ers as implantable sensors to monitor the sleep of pa- tients because they con- form to internal organs with- out causing any adverse re- actions. Athletes could also use the technology to mon- itor their health while exer- cising and swimming. These stickers are pat- terned in serpentine shapes to make the devic- es as thin and stretchable as skin, making them im- perceptible for the wearer. Since paper degrades fast when it gets wet and human skin is prone to be covered in sweat, these stickers were coated with molecules that repel wa- ter, oil, dust and bacteria. Each sticker costs about a nickel to produce and can be made using printing and manufacturing technologies similar to those used to print books at high speed. "The low cost of these wearable devices and their compatibility with large- scale manufacturing tech- niques will enable the quick adoption of these new fully disposable, wearable sen- sors in a variety of health care applications requiring single-use diagnostic sys- tems," Martinez said. The technology is patent- ed through the Purdue Of- fice of Technology Commer- cialization. They are con- tinuing to look for partners to test and commercialize their technology. Purdue University researchers have created wearable electronic devices that someone can easily attach to their skin. The devices are made out of pa- per to lower the cost of personalized medicine.
