Greg Waite, CEO of InventionShare™, announced from its Ottawa office today that InventionShare’s Circuit Seed family of digital circuit designs for processing analog signals can provide more lifesaving protection and perform more accurate measurements by integrating these circuit designs into the next generation of fitness trackers made by major manufacturers.
Mr. Waite was commenting on a recent study by researchers at Stanford University School of Medicine that looked at seven popular fitness trackers from well-known companies such as Apple, Basis Peak, Fitbit, Microsoft, Milo and Samsung. The study consisted of a group of volunteers who wore one of the devices and an electrocardiograph. Their metabolic rates were estimated with a device that measured oxygen and carbon dioxide levels in their breath, while running on treadmills or using stationary bicycles. Link here
As part of the study, various observations were made. “The heart-rate measurements performed far better than we expected, but the energy expenditure measures were way off the mark,” said Euan Ashley, professor of cardiovascular medicine, genetics and biomedical data science at Stanford, and the senior author of the study. “The magnitude of just how bad they were surprised me. People are basing life decisions on the data provided by these devices.” Also, none of the devices measured the number of calories burned.
The study concluded that the least accurate was the Samsung Gear 2, which was off by a significant 93%, while the Apple Watch had the lowest overall error rate at 27%. Although the study was inconclusive on heart rate monitoring, Fitbit has had issues in the past in regards to heart rate tracking. Link here
Mr. Waite said, “We think that the whole issue surrounding fitness tracker type devices is that the sensors being used in the products just do not have the necessary accuracy. While there are many breakthroughs in the design of current sensors on the market, many are working at lower ranges of effectiveness due to the analog components currently found in their designs. While sensors, imaging, communications and microprocessors are currently operating at significantly high speeds, eliminating the analog components and using Circuit Seed’s digital designs that do all the signal sensing and signal processing in one universal programmable chip can save micro-seconds, providing much more accurate measurements and perhaps even saving lives from reducing the risk of heart attacks or failure by providing accurate heart monitoring.”
Through InventionShare, Circuit Seed is currently working with several OEMs, semiconductor and sensor manufacturers and is looking to partners for broad adoption of the technology in a variety of industry areas and is looking forward to discussions in the fitness and fitness tracker industry. The company is also rolling out a spin-off company Sensory Seed™ which focuses on the design of near market circuits for health and life sciences applications to improve current and future health and fitness wearables, medical device diagnostics, monitoring and therapeutics.
