Purpose

• Evaluating soft artificial skin-like material with pressure sensibility using FSR sensors.

Design

• The design of the project will be a skin platform that will consist of an embedded grid of FSRs that are spatially arranged.

• The platinum silicone will then be poured on top of the grid.

History of FSR Sensor

• (FSR) was invited in 1977 by Franklin Eventoff.

The equation above is the output from a FSR device.

FSR Sensor

• Uses polymer film, which triumphs over traditional force sensing devices.

• These sensors have a wide measurable force range.

• Occupy is minimal space.
