A multimodal measurement of the impact of deepfakes on the ethical reasoning and affective reactions of students

Touradj Ebrahimi, Patrick Jermann, Roland John Tormey, Cécile Hardebolle, Vivek Ramachandran, Nihat Kotluk

Deepfakes - synthetic videos generated by machine learning models - are becoming increasingly sophisticated. While they have several positive use cases, their potential for harm is also high. Deepfake production involves input from multiple engineers, maki ...

Enhancement of Pressure-Sensitive Adhesive by CO2 Laser Treatment

Dario Floreano, Vivek Ramachandran, Yegor Piskarev, Jun Shintake, Michael Dickey, Jianhang Yang

Pressure-sensitive adhesives (PSAs) are polymeric films that can be adhered to and detached from surfaces without leaving residue. Researchers are looking to enhance the bond strength between PSAs and different substrates. It can be achieved by tuning PSA' ...

Arm-wrist haptic sleeve for drone teleoperation

Dario Floreano, Vivek Ramachandran, Matteo Macchini

Teleoperators rely on both visual and haptic feedback to perform drone teleoperation tasks, such as obstacle avoidance. Haptic feedback becomes essential when visual feedback is compromised, either due to visual occlusions or poor depth perception. However ...

Smart Textiles that Teach: Fabric‐Based Haptic Device Improves the Rate of Motor Learning

Dario Floreano, Vivek Ramachandran, Amy Roning Wu, Fabian Maximilian Schilling

People learn motor activities best when they are conscious of their errors and make a concerted effort to correct them. While haptic interfaces can facilitate motor training, existing interfaces are often bulky and do not always ensure post-training skill ...

Lighter and Stronger: Cofabricated Electrodes and Variable Stiffness Elements in Dielectric Actuators

Dario Floreano, Vivek Ramachandran, Yegor Piskarev, Jun Shintake, Michael Dickey

The inherent compliance of soft robots often makes it difficult for them to exert forces on surrounding surfaces or withstand mechanical loading. Controlled stiffness is a solution to empower soft robots with the ability to apply large forces on their envi ...

Haptic feedback perception and learning with cable-driven guidance in exosuit teleoperation of a simulated drone

Dario Floreano, Auke Ijspeert, Vivek Ramachandran, Amy Roning Wu, Carine Rognon

Robotics teleoperation enables human operators to control the movements of distally located robots. The development of new wearable interfaces as alternatives to hand-held controllers has created new modalities of control, which are more intuitive to use. ...

All‐Fabric Wearable Electroadhesive Clutch

Dario Floreano, Vivek Ramachandran, Jun Shintake

A lightweight, textile fabricated, haptic device consisting of an electrostatic adhesive clutch is introduced, which can constrain body movement when activated at low power (≈1 mW). The clutch electrodes are composite structures, prepared by coating copper ...
