Abstract

This paper reports the acoustothermal heating of wet papers using surface acoustic wave (SAW). The proposed heating method utilizes ultrasonic absorption of waterlogged paper, which exhibits viscoelastic properties. The surface acoustic waves propagate on the piezoelectric substrate and refract into a wet paper strip on the substrate. The refracted longitudinal waves deliver acoustic energy into the wet paper by vibration damping in the form of heat. Acoustothermal heating was discovered to be frequency-dependent and to reach local maxima at certain frequencies. Based on this finding, we developed a paper microfluidic heating system for point-of-care (POC) glucose detection.
