Internet of things platform for real-time intraoral forces monitoring

In the Internet of Things era, medical devices shall be miniaturized and connectable to the global network for exchanging patient data. In this work, the miniaturization of a device for wireless intraoral forces monitoring is presented. Strain gauges are used as force sensors detecting tongue and lips activities. Signal elaboration has been demanded to an STM32NUCLEO-F401RE board while wireless data transmission using Bluetooth® Low Energy standard protocol is obtained by means of a XNUCLEO-IDB04A1 board. The circuit has been further miniaturized using a SoC based on Nordic nRF51422 that features an ANT and Bluetooth® low energy transmission and an ARM Cortex-M0 core. The final device shows a reduced dimension and the ability to transmit data wirelessly, without the use of external cables normally used in state-of-the-art intraoral monitoring devices.
