Development of Prototype Module for Temperature Sensing in Biological Tissues

A new approach for sensing temperature change in biological tissue by using 3D printed prototypes has proposed. The temperature change on the surface of tissue was measured at different wavelength of light. LM35, Thermistor, Light Dependent Resistor (LDR) and Photodiode were used as sensing element in the prototype. The experiment was conducted at room temperature and maintained the surrounding temperature at 37 ± 2 °C. The temperature change in solutions with different concentrations of salt and sugar were measured using sensing prototypes. Multiple graphs are plotted to compare temperature changes with respect to time and light intensities.
