Researching on the adhesive properties of elastic materials ( silicone, hydrogels, etc. ) with surface features adhesive effect by using JKR ( John, Kendall and Roberts) theory is an important section in material science. Thus, it is necessary to develop JKR energy measuring instrument to provide reliable experimental platform for such research. Based on JKR theory, by adopting virtual instrument technology, the design and development of the hardware and software system of JKR energy instrument are conducted. The JKR experimental platform is established successfully, the JKR data acquisition is implemented and the system is tested and verified. The result of test shows that this instrument possesses many advantages including ease and flexible operation, scientific structure design, and high operating accuracy, etc.
