Lie Detector

This isometric 3D lie detector icon represents a polygraph machine used in forensic, psychology, and examination settings. It works well in investigation visuals, medical device collections, educational content, and security themed interfaces. Free to download, it adds a clear and professional touch to modern designs.

Every Lie Detector detail is modelled at the same scale and lit the same way as the rest of Thridy's 3D icons, which is what keeps a set looking deliberate. It is an isometric 3D render, on a transparent background, with no mask to draw.

Used alongside other Health & Fitness icons it holds its weight visually, so a row of them looks composed rather than assembled.

Common homes for it are health dashboards, appointment booking flows, workout trackers and wellness landing pages. Teams in healthtech, telemedicine, gyms and wellness brands tend to use it most. Download it free, or request a custom variation if your project needs a different angle, colour or companion icon.
