This paper describes the effect of suction cup with bioinspired microstructure on suction force and self-adhesive force. The suction cups generate the negative pressure by deforming a membrane. Moreover, the suction cups have the grooves imitating octopus and pentagonal projections imitating lumpfish. It has been reported that the adhesiveness was increased by these microstructures on suction cup of aquatic organisms. The measured suction force was range from 50 to 60 N. The suction force was increased using suction cup with microstructure. The contact area between object and suction cup with microstructure was low. The contact area was lower, the suction force was higher. The measured selfadhesive force was range from 4 to 6 N. The self-adhesive force was decreased using the suction cup with microstructure, because of the low contact area. However, the peeling time was longest using the suction cup with circular grooves. The negative pressure was generated in the grooves by pressing suction cup.
