Hand and face somatotopy shown using MRI-safe vibrotactile stimulation with a novel soft pneumatic actuator (SPA)-skin interface
Jamie Paik, Harshal Arun Sonar
The exact somatotopy of the human facial representation in the primary somatosensory cortex (S1) remains de-bated. One reason that progress has been hampered is due to the methodological challenge of how to apply automated vibrotactile stimuli to face area ...
ACADEMIC PRESS INC ELSEVIER SCIENCE2023Comprehensive Interactive Soft Interfaces for Wearable Tactile Feedback
As the field of robotics continues to grow outside the manufacturing environment into our daily lives, the interactions between humans and robots are increasingly becoming close and dynamic. This type of environment requires robots to be less rigid, multi- ...
EPFL2021Soft Touch using Soft Pneumatic Actuator-Skin as a Wearable Haptic Feedback Device
Jamie Paik, Harshal Arun Sonar, Jian-Lin Huang
Understanding the external environment depends heavily on vision, audition, and touch. Like vision and audition, the human sense of touch is complex. Tactile perception is composed of multiple fundamental and physical experiences felt as changes in stiffne ...
WILEY2021Flow Path Optimization for Soft Pneumatic Actuators: Towards Optimal Performance and Portability
Jamie Paik, Harshal Arun Sonar, Sagar Dattatray Joshi
Soft pneumatic actuators (SPAs) are highly desirable for interactive robotics applications owing to their unconventional properties like high compliance, safe human-machine interaction and adaptable design space. The SPA dynamic behaviour is governed by pn ...
IEEE-INST ELECTRICAL ELECTRONICS ENGINEERS INC2021Age-Dependent Asymmetry of Wrist Position Sense Is Not Influenced by Stochastic Tactile Stimulation
Jamie Paik, Olivier Lambercy, Harshal Arun Sonar
Stochastic stimulation has been shown to improve movement, balance, the sense of touch, and may also improve position sense. This stimulation can be non-invasive and may be a simple technology to enhance proprioception. In this study, we investigated wheth ...
2020Closed-Loop Haptic Feedback Control Using a Self-Sensing Soft Pneumatic Actuator Skin
Stéphanie Lacour, Jamie Paik, Harshal Arun Sonar, Aaron Powers Gerratt
In this article, we achieve a closed-loop control over haptic feedback, first time for an entirely soft platform. We prototyped a novel self-sensing soft pneumatic actuator (SPA) with soft strain sensors, called SPA-skin, which withstands large multiaxial ...
2019An Any-Resolution Distributed Pressure Localization Scheme Using a Capacitive Soft Sensor Skin
Jamie Paik, Harshal Arun Sonar, Michelle Ching-Sum Yuen
We present a method to determine the location of an applied pressure on a large area, monolithic silicone based capacitive sensor. In contrast to pressure sensor arrays composed of n x n discrete sensors, we utilize a single sensor body with a single instr ...
2018A soft portable wearable pneumatic interactive suit
Jamie Paik, Matthew Aaron Robertson, Harshal Arun Sonar, Sagar Dattatray Joshi, Tigmanshu Bhatnagar
A fully wearable system used for communication and information transfer between two users or between a user and a machine to render an effective and intuitive physical interface for combined input and output functions, the fully wearable system including a ...
2018A reconfigurable interactive interface for controlling robotic origami in virtual environments
Jamie Paik, Harshal Arun Sonar, Zhenishbek Zhakypov, Jian-Lin Huang
Origami shape transformation is dictated by predefined folding patterns and their folding sequence. The working principle of robotic origami is based on the same principle: we design quasi-two-dimensional tiles and connecting hinges and define and program ...
2018Design and Computational Modeling of a Modular, Compliant Robotic Assembly for Human Lumbar Unit and Spinal Cord Assistance
Jamie Paik, Matthew Aaron Robertson, Harshal Arun Sonar, Gunjan Agarwal
Wearable soft robotic systems are enabling safer human-robot interaction and are proving to be instrumental for biomedical rehabilitation. In this manuscript, we propose a novel, modular, wearable robotic device for human (lumbar) spine assistance that is ...
