Electrical Generation of Intranasal Irritating Chemosensation

Percutaneous electrical stimulation modifies brain and nerve excitability and also stimulates various sensory organs.Although it can be applied to sensory information displays, virtual reality, and human augmentation, the effect on human intranasal chemosensation, including olfaction, is not clearly understood.In this paper, we introduce galvanic o

Design and evaluation of a quasi-zero-stiffness isolator using flexibly supported negative stiffness mechanism

In traditional quasi-zero-stiffness (QZS) isolation system, the Tubing Cutter negative stiffness part is usually fixed rigidly, lacking of effective amplifying mechanism.For reaching a quasi-zero state, the value of negative stiffness need to be very large to offset the positive stiffness of the structure.This paper proposes a novel isolator incorp
