Touching the microworld

What if you could touch objects smaller then the width of your hair and perceive their universe ?

 

This is the aim of IOTA Project, funded by ANR France. We are using the power of light to manipulate cells and molecules, and let the user control and feel the interaction with his fingertips.

Fundamental mechanisms of the Universe stem from the microscale phenomena

Understanding and controlling small scales is the current challange in Physics, Biology, Chemistry & Engineering

  • An interactive instrument for exploration, manipulation and characterization at small scales
  • Biomedical applications, microassembly
  • Tactile force-feedback user interface
  • Transscale coupling and natural interaction

A Brand-NEw Scientific instrument

Optical Tweezers

2018 Nobel prize in Physics were awarded to A. Ashkin for Optical Tweezers. We take it one step further by integrating real-time high-band force feedback, measuring interactions forces in picoNewton range

Surface haptics

Directly modifying the friction of the bare finger sliding on glass using ultrasonic vibrations enables the production of virtual relief, texture and buttons on touchscreens.
