An artificial elementary eye with optic flow detection and compositional properties

Dario Floreano, Michal Karol Dobrzynski, Ramon Pericet Camara

We describe a 2 mg artificial elementary eye whose structure and functionality is inspired by compound eye ommatidia. Its optical sensitivity and electronic architecture are sufficient to generate the required signals for the measurement of local optic flo ...

Miniature curved artificial compound eyes

Dario Floreano, Michal Karol Dobrzynski, Ramon Pericet Camara, Géraud L'Eplattenier

In most animal species, vision is mediated by compound eyes, which offer lower resolution than vertebrate single-lens eyes, but significantly larger fields of view with negligible distortion and spherical aberration, and high temporal resolution in a tiny ...

Hyper-flexible 1-D shape sensor

Dario Floreano, Michal Karol Dobrzynski, Ramon Pericet Camara, Géraud L'Eplattenier, Stéphanie Lacour

Here we describe a sensor capable of perceiving complex one-dimensional (1-D) shape of an underlying substrate in a static and dynamic manner. The sensor consists of seven, serially connected, hyper-flexible strain gauges, manufactured using stretchable-go ...

Quantifying information transfer through a head attached vibrotactile display: principles for design and control

Dario Floreano, Michal Karol Dobrzynski, Seifeddine Mejri

Vibrotactile displays can extend the perception capabilities of visually impaired persons. Placing such devices on the head promises easy attachment and detachment without reducing other interaction abilities. However, the effectiveness of head-attached vi ...

Contactless deflection sensing of concave and convex shapes assisted by soft mirrors

Dario Floreano, Ionut Halasz, Michal Karol Dobrzynski, Ramon Pericet Camara

Typical deflection sensors like strain gauges or devices based on optical fibers require physical contact with the deflected substrate during the measurement process. Such contact, however, impacts on the softness of the substrate and may falsify the measu ...

Contactless deflection sensor for soft robots

Dario Floreano, Michal Karol Dobrzynski, Ramon Pericet Camara

In the emerging field of soft robotics, there is an interest in developing new kinds of sensors whose characteristics do not affect the intrinsic compliance of soft robot components. Additionally, non-invasive shape and deflection sensors may provoke impro ...
