Determining the performance of a temperature sensor embedded into a mouthguard

L. D. A. E. Bueno, W. Milnthorpe, et al.

This innovative study investigates the steady-state errors of oral-based temperature sensors in mouthguards, achieving remarkable accuracy with a mean absolute error of just 0.2 °C after a short duration. Conducted by Leonardo de Almeida e Bueno, William Milnthorpe, and Jeroen H. M. Bergmann from the University of Oxford, the research highlights the potential of instrumented mouthguards in clinical applications while addressing the need for timely temperature stabilization.

Abstract
This study aimed to determine the steady-state errors of oral-based temperature sensors embedded in mouthguards. Four electronic boards with temperature sensors were encapsulated in mouthguards and tested in a thermostatic water bath at 34, 38.5, and 43 °C. A mean absolute error of 0.2 °C was reached after a maximum of 690 s. A case study showed an absolute error of 0.2 °C after 1110 s. The instrumented mouthguard yielded consistent steady-state error close to clinical requirements, but the time to reach steady-state temperature needs consideration.
