Aptamer-functionalized capacitive biosensors
The growing use of aptamers as target recognition elements in label-free biosensing necessitates corresponding transducers that can be used in relevant environments. While popular in many fields, capacitive sensors have seen relatively little, but growing ...
20233D printing of elastomeric mechanical sensors designed for human motion monitoring
In this thesis several advances are made to the emerging field of 3D printed mechanical sensors. Techniques and processes were developed to enable the integration of highly conductive, and capacitive and piezoresistive sensing features embedded within 3D p ...
EPFL2022Using redundant and disjoint time-variant soft robotic sensors for accurate static state estimation
Josephine Anna Eleanor Hughes, Antonia Georgopoulou Papadonikolaki
Soft robotic sensors have been limited in their applications due to their highly nonlinear time variant behavior. Current studies are either looking into techniques to improve the mechano-electrical properties of these sensors or into modelling algorithms ...

The present invention concerns an elongated capacitive sensor (1) for fluid monitoring. The sensor (1) comprising: a fibre support (5) made of a dielectric material or dielectric composite material; and a first electrode (7, 9) and a second electrode (7, 9 ...
2021Haptigami: a fingertip haptic interface with vibrotactile and 3-DoF cutaneous force feedback
Jamie Paik, Sagar Dattatray Joshi, Frédéric Henri Vaskin Giraud
Wearable fingertip haptic devices aim to deliver somatosensory feedback for applications such as virtual reality, rehabilitation, and enhancing hardware/physical control interfaces. However, providing various kinds of feedback requires several Degrees of F ...
2021Ultrasoft Liquid Metal Elastomer Foams with Positive and Negative Piezopermittivity for Tactile Sensing
Yegor Piskarev, Yang Li, Michael Dickey, Jianhang Yang
Soft, capacitive tactile (pressure) sensors are important for applications including human-machine interfaces, soft robots, and electronic skins. Such capacitors consist of two electrodes separated by a soft dielectric. Pressing the capacitor brings the el ...
WILEY-V C H VERLAG GMBH2020TacTiles: Dual-Mode Low-Power Electromagnetic Actuators for Rendering Continuous Contact and Spatial Haptic Patterns in VR
Herbert Shea, Juan José Zarate, Ronan Julien Hinchet
We introduce TacTiles, light (1.8g), low-power (130 mV), and small form -factor (1cm(3)) electromagnetic actuators that can form a flexible haptic array to provide localized tactile feedback. Our novel hardware design uses a custom 8 -layer PCB, dampening ...
IEEE2019Sensorimotor processing in the rodent barrel cortex
Tactile sensory information from facial whiskers provides nocturnal tunnel-dwelling rodents, including mice and rats, with important spatial and textural information about their immediate surroundings. Whiskers are moved back and forth to scan the environm ...
NATURE PUBLISHING GROUP2019Closed-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 ...
