But while he has seen one unnamed company attempt to develop a workable device for more than 10 years, "Google has the big money to pull it off." "Google's smart pill and wearable may not launch in five years, but it could eventually bend the technology curve," Prakash said. "If anybody can do this, Google can, since they can invest billions of dollars in the project and have the tal- ent to pull it off." Higher-Powered Wearable Sensors University of Michigan researchers have developed a wearable sensor that they claim can detect diabetes, high blood pressure, anemia, and lung disease more accurately by using more high-powered and sensitive sensors than have previously been developed. The researchers sought to develop a device to overcome the problems posed by previous monitoring devices, such as slow detection rates due to the strong bonds between the molecules being detected and the sensor itself. The resulting wearable has more reactive sensors by using hetero- dyne mixing instead of molecular charges to detect chemical changes in the body. Other chemicals it could detect include nitric oxide and oxygen, abnormal levels of which can point to conditions such as high blood pressure, anemia, or lung disease. "This technology is a more promising development with the poten- tial to disrupt the medical device space," Prakash said. "But its availability is a few years off at least. Think of it as one of several pieces in a larger puzzle of poten- tial yet promising wearable applications that could see launch in the future." Skin-Like Wearable Device Monitors Heart Health Cardiologists hope to eventually benefit from around-the-clock ECG monitoring devices that patients could comfortably wear for days or even weeks at a time, without interfering with their daily lives. California State University researchers believe they may have developed a solu- tion. They are working on improving the detection of arrhythmias and other heart abnormities by testing a less-obtrusive alternative with medical device maker iRythm that patients can wear for longer periods of time than existing devices. The researchers have begun testing small and wearable cardiac monitoring devices that wearers hardly notice when attached to their chest, thanks to their small size of only 5 cm. The devices are designed to attach directly to the skin in such a way that patients hardly notice they are there, according to the researchers. The waterproof patches contain two main low-power chip components: a system-on-a-chip device with a sensor and microprocessor along with a communica- tions device with Bluetooth connectivity. While noting that long-term studies and testing are required to determine the patches' viability, the researchers and ana- lysts alike believe that long-term monitor- ing for heart disease with miniaturized patches is feasible. "The skin-like patch is capable of tracking cardiovascular disease in a portable and non-intrusive way—and with a much lower price tag," Allada said. Smaller The number of companies you can trust.
