A typical sheet of paper or cardboard is neither waterproof, interactive or able to harvest energy, but an innovative new printing technology developed at Purdue University can make it all of the above. The researchers demonstrated the technique by transforming a sheet of notebook paper into a music player, and say it could be scaled up to work with larger printing processes for more mainstream uses. “This is the first time a self-powered paper-based electronic device is demonstrated,” says study author Ramses Martinez, an assistant professor in Purdue’s School of Industrial Engineering. “We developed a method to render paper repellent to water, oil and dust by coating it with highly fluorinated molecules. This omniphobic coating allows us to print multiple layers of circuits onto paper without getting the ink to smear from one layer to the next one.” With this omniphobic coating as the starting point, the researchers were able to integrate vertical pressure sensors onto the paper. This not only enables it to become an interactive surface for a variety of applications, but also one that can harvest energy from user’s actions through friction as they apply pressure to the device, which can be used to power wireless Bluetooth communication.
CJK Group, Inc. has announced that it has permanently raised the starting hourly wage to $15 for U.S. workers. The wage increase is a welcomed benefit to current employees as well as strengthening opportunities to attract new hires.
The current labor shortage in America and the company’s tenacity to be an employer of choice, served as catalysts toward the decision to increase the minimum wage. To remain strong and competitive in the marketplace and aggressively expand in the government sector, CJK Group recognizes the need to continue to position itself as a preferred workplace.
Rather than simply providing jobs, CJK Group is proud to offer its employees careers. The length of tenure at each of its companies is truly astounding, with some team members working diligently for 40+ years. This investment in raising the minimum wage for U.S. workers is another important step that CJK Group is taking to continue to add the best and the brightest job seekers to its already highly talented team.
