Wearable Electrohydraulic Actuation For Salient Full‐Fingertip Haptic Feedback

Advanced Materials Technologies, EarlyView.
This study introduces a wearable soft robotic system that combines a flat and conformable electrohydraulic pump, a mechanically transparent channel, and an ultra‐thin fingertip chamber to provide salient haptic feedback that imitates natural touch experiences.

Multi‐Stamping on Multi‐Prestrain (MSMP) Process for Multifunctional Wearable Bioelectronics with Optimized Electromechanical Properties

Advanced Materials Technologies, EarlyView.
A novel multi‐stamping on multi‐prestrain (MSMP) process is proposed, where sensor elements are transferred onto a substrate under different prestrains (0–150%) within a single integrated platform. This MSMP approach not only resolves the mismatch issue in stretchable wearable electronics, but also ensures that each sensor element exhibits optimal ...

Looking at Hands in Autonomous Vehicles: A ConvNet Approach using Part Affinity Fields [PDF]

arXiv, 2018
In the context of autonomous driving, where humans may need to take over in the event where the computer may issue a takeover request, a key step towards driving safety is the monitoring of the hands to ensure the driver is ready for such a request. This work, focuses on the first step of this process, which is to locate the hands.
