The tactile display is an important tool to help humans interact with machines through touch. In this paper, we present a multi-array tactile display device with dielectric elastomer actuator (DEA). The device uses the fluid coupling between the contact point and the actuator as power transmission. It is designed to ensure comfort of touch and safety of operation for the users during contact with human skin.
The principle of operation is explained in detail and a systematic design analysis is given. The displacements of the tactile display are about 240-120 m at 3-10 Hz, which meets the frequency requirements for simulating the Merkel cells and Meissner corpuscles, and the force is more than 40 mN to simulate the fingertip. In addition, a special manufacturing method and performance measurements are explained.
The Array Designer app lets you interactively design, visualize, and analyze arrays in the Antenna Toolbox™ library.
With this app you can:
- Show different array configurations and layouts that define element spacing.
- Compare different types of arrays and answers.
- Choose an array configuration to meet specific peak gain, directivity, desired coverage, pattern, gate parameters.
- Change the spacing between the elements and see the effect on the performance of the array.
- Visualize the effect of interconnection in port and in the far field.
- Optimize arrays for different analysis results under certain constraints using SADEA or surrogate optimization methods.
