Abstract

This article presents microfabricated platinum resistance temperature detector (platinum RTD) to measure the temperature change of deformed red blood cells when they were heated by laser irradiation. The thermometer was fabricated with platinum thin layer using a microelectromechanical system (MEMS) technique. The platinum RTD has 2μm of electrode width with serpentine shaped platinum element and sensitivity of the platinum RTD is 643.8 mΩ/°C. For specific heating of red blood cells, 1 to 300mW power tunable diode pumped solid state (DPSS) laser module was used with 532nm wavelength. The temperature changes of puffed, normal, and shriveled red blood cells are around 6.3°C, 13.2°C, and 19.8°C respectively at 300mW maximum laser power.
