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 — like a saliva reader that’s so tiny it can be mounted onto a tooth.
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, ...
