  1. Hosting material: 10 g fatty acid (myristic, palmitic and stearic) + 30 ml gelatin (10%). PCM material: 10% coconut or octadecanol.
  2. To: Onset Temperature, Tp: Keeping Temperature, \(\Delta\)H: Enthalpy.
  3. Duration index: based on \(\Delta\)T from melt point to body temperature (37 °C) and average density of 0.8 \({\text{g}/\text{cm}}^{3}\)
