xG27 (health monitoring chips)

2023: Health Monitoring Chip Announcement

On March 14, 2023, Silicon Labs announced tiny microchips of the xG27 family designed for use in a variety of medical devices. The products are so small that they can be attached to the tooth for ongoing health monitoring.

The series includes BG27 and MG27 solutions: both use Arm energy-efficient Cortex M33 cores. At the same time, the first of these chips supports wireless communication, and Bluetooth the second - Zigbee and some other protocols. The area of ​ ​ the products varies from 2 to 5 square meters. mm, which can be compared with the diameter of the pencil rod and the width of the pencil itself, respectively. These are not the smallest Bluetooth chips in the world, but a Silicon Labs spokesman claims that the difference with the smallest products is "a fraction of a millimeter."

xG27

Medical device manufacturer Lura Health has already created a sensor module on the basis of one of the chips of the xG27 family, which can be mounted on a tooth to analyze the composition of saliva. This sensor allows you to track approximately 1000 parameters, which gives medical personnel the ability to quickly identify deviations from the norm that indicate the possible development of certain diseases. Lura Health claims that it has already completed clinical trials of its product with the support of UConn Orthodontics specialists: the novelty may appear on the commercial market in 2024.

Among other options for using chips xG27 Silicon Labs names smart medical patches, devices for continuous glucose monitoring and compact wearable removal devices. ECG The products can function at a voltage of only 0.8 V, so they can be content with compact low-power power supplies. In addition, a storage mode is provided to minimize energy consumption.^[1]
