With growth in the smart wearables market, more and more consumers have access to convenient, user-friendly continuous data monitoring devices. However, there’s still potential for this technology in the critical diagnostics space.
The New Blood: Saliva
Saliva, the extracellular fluid secreted by salivary glands in the mouth, can be used to test for a wide range of health conditions, containing potentially over 1,000 biomarkers such as the body’s pH (acidity), glucose levels, electrolyte count, and more. It’s an incredibly data-rich medium. Today, saliva monitoring occurs via one-time measurements at point-of-care facilities; however, since saliva offers evolving insights into a patient’s condition, one-time measurements, even taken regularly, leave out critical information that can only be obtained through continuous monitoring.
To address this gap in preventative care, Lura Health designed the world’s first continual salivary health monitor to improve oral and systemic health and reduce out-of-pocket spending on health care.
To develop a continual salivary health monitor that can be worn inside the mouth to track oral and systemic health.
Silicon Labs EFR32BG27 small Bluetooth SoC features an ultra-small WLCSP package with low power consumption, Bluetooth connectivity, and sizable memory for connected medical devices, wearables, sensors, switches, and more.
The Oral Acid Monitor is a first-of-its-kind design and one of the smallest IoT devices in the world.
Getting Down to Size with our Small Bluetooth Chip
Lura Health’s Oral Acid Monitor includes a sensor worn in the mouth that takes continual saliva readings and transmits data to the patient’s smartphone via a secure Bluetooth connection. The associated smartphone app provides real-time health alerts and clear, intuitive data analysis for patients and doctors alike.
While the device is still in development and not currently approved for sale or distribution in the United States, the team is going to market with a smart retainer design that features a small module embedded in high-quality, transparent plastic. With access to better and better technology, Lura Health is experimenting with two other configurations. One design has the module bonded to a ring that fits around the tooth, and the other design is small enough to be bonded directly to the surface of a tooth. No microcontroller on the market has been small enough to accommodate a tooth-mounted design until the release of Silicon Labs small Bluetooth LE SoC, the BG27.
