Future research works could focus on the following areas to improve the performance the
system. First, the gap between a peltier and a heat sink should be closed by filling it up with
high-quality silicone as the gap reduces the heat transferred between the peltier and the heat
sink. Second, the PID control method could be applied to the proposed system as it expedites
the blood warming and thereby requires even less amount of time to reach the pre-set
temperature
