Recognizing the coming "silver tsunami" of graying baby boomers, tech companies are racing to help aging Americans spend more time living independently instead of in nursing homes. For the first time earlier this month, the International Consumer Electronics Show in Las Vegas featured a special section devoted to high-tech senior living.
Among the advances at the show were motion sensors, the kind that allowed Olweean's nurses to figure out what was keeping her up at night. She was experiencing excessive bloating, a common symptom of congestive heart failure. So Olweean's cardiologist prescribed diuretics and made other adjustments to her medication that helped the woman again sleep soundly.
"We try to identify when those small problems occur, so we can fix them before they become big problems," said Marjorie Skubic, an electrical and computer engineering professor who works with Sinclair School of Nursing researchers on the aging-in-place project.
At Oatfield Estates in the Portland suburb of Milwaukie, Ore., resident movements in the private retirement home are tracked by what employees call "bed bugs." Those are embedded motion sensors that detect when someone's behavior could trigger a medical alert.
Sensors like those, "smart carpets" and other tracking devices will be the norm in both private homes and group settings within the next decade, said Jason Hess, chief executive officer of Elite Care, the Portland company that owns Oatfield Estates. He said that will especially be true as insurers start embracing the cost-saving devices.
"You will see a lot more places implementing these," he said. "It comes down to cost, and out-of-the-box thinking."
At the Las Vegas show, on display were talking pill boxes that remind seniors to take their medicine at regular intervals, and which can notify out-of-town caregivers if that doesn't happen. There were robotic companion pets that mimic the real thing for lonely seniors in need of a psychological boost.
"We're talking about an important paradigm shift in how we think about aging," said Majd Alwan, director of the Washington-based Center for Aging Services Technologies. Alwan led a panel discussion on smart-home technology at the Las Vegas event.
Delaying institutionalization by a year or more, is a significant financial savings, he added. "Let alone the benefits in quality of life for the senior and for the caregiver."
Alwan previously led the eldercare technology unit of the University of Virginia's Medical Automation Research Center, which developed the passive sensor technology used in Missouri.
