Abstract
The objective of this thesis is to identify actuation technologies for active tactile surfaces. Such surfaces are envisioned to change texture when given an electrical input. One way to change texture is to create button-like protrusions of different sizes. This technology is expected to combine the advantages of touchscreens and tactile buttons to create refreshable tactile surfaces. Suitable technologies that can be used to create protrusions are initially studied in a literature review. Based on the conclusion of comparative study in the literature survey, shape memory alloys are selected as the smart material and various actuators are built using SMA wires. Conical springs are used as SMA actuators and a 3 x 3 array is built. Modeling of the force versus deflection curve of helical and conical shape memory alloy springs is also presented.
