Abstract We have demonstrated the feasibility of a gummy bear-based gnathodynamometer for masticatory diagnostics. Using a gummy bear as a force transducer and bamboo cantilevers as mechanical springs, the masticatory force of a human mandible can be measured via electrical impedance measurement (presented as the output voltage of the gnathodynamometer). The frequency response of the gummy bear is experimentally tested from 0.1 to 100 kHz and shown to be consistent with the analytical model. For a given driving frequency, the output voltage of the gnathodynamometer is experimentally measured for a range of stimulated masticatory forces (˜3.49 to 88.50 N). The masticatory force limit is also adjustable via the driving frequency (10 to 100 kHz) and cantilever length (via sliding datum, L = 95, 75, and 50 mm). This also adjusts the masticatory force sensitivity in the range of ˜17.5 to 40.5 mV/N. The clinical feasibility is also evaluated using three human subjects. The combination of candy (gummy bear) and diagnostics heralds a new class of low-cost medical devices that generate minimum recalcitrant medical waste and that are suitable for developing countries.
