Miniaturizing tech is a perpetual challenge for wearable makers. The smaller the device, the better it is for wearability. The thing is, that usually comes at the expense of battery life. However, Silicon Labs is hoping its latest xG27 chipset is small and energy-efficient enough to spark some big ideas in the medical tech space \u2014 like a saliva reader that\u2019s so tiny it can be mounted onto a tooth. <\/p>\n

According to Silicon Labs, the xG27 family of SoCs consists of the BG27 and the MG27. Both are built around the ARM Cortex M33 processor, but the BG27 focuses on Bluetooth, while the MG27 supports Zigbee and other protocols. As for how small these chips are, the xG27 SoCs range from 2mm-squared to 5mm-squared \u2014 roughly the width of a No. 2 pencil\u2019s lead tip to the width of the pencil itself. It\u2019s not the world\u2019s smallest Bluetooth chip, but Silicon Labs spokesperson Sam Ponedal tells The Verge<\/em> that\u2019s only by \u201cfractions of a millimeter.\u201d<\/p>\n

This is neat from a technical perspective, but what\u2019s cooler is the BG27 is currently being used to develop an actual product \u2014 the aforementioned tooth-mounted wearable sensor. Lura Health<\/a>, a medical device maker, says it\u2019s using the chip for its \u201csalivary diagnostic sensor.\u201d The sensor is small enough to be glued to a molar (or placed inside a \u201csmart retainer<\/a>\u201d) with the intent of continually monitoring a patient\u2019s saliva. That, in turn, would allow dentists and clinicians to potentially test for more than 1,000 health conditions. <\/p>\n

This wouldn\u2019t be the first time that a company has pitched this kind of futuristic health tech. But while most attempts are thwarted by the FDA regulatory process<\/a>, Lura Health claims it has just finished clinical trials for the sensor with UConn Orthodontics and is currently preparing to undergo the FDA regulatory process. If all goes well, the product could hit the market in 12-18 months. <\/p>\n

As for other use cases, Silicon Labs says its chips are good candidates for medical patches, continuous glucose monitors, and wearable EKGs. That\u2019s because they can operate on as low as 0.8 volts and can switch to a \u201cshelf mode\u201d that reduces energy use during transportation and while stored on shelves. These features aren\u2019t quite as appealing in consumer wearables, but it opens the door for greater wearable use in hospitals and clinical settings.<\/p>\n<\/div>\n
