Design of Highly Stretchable, Self‐Adhesive Ionic Conductive Hydrogels for Wearable Strain Sensors

open access: yesAdvanced Sensor Research, EarlyView.
A novel ionic conductive hydrogel is achieved by introducing phytic acid into semi‐interpenetrating cross‐linked network of poly(acrylamide‐co‐N‐(hydroxymethyl) acrylamide) and chitosan hydrogels, which exhibits high stretchability, favorable electrical conductivity, reversible adhesiveness, and excellent strain sensing performance, simultaneously ...

A Convoy of Magnetic Millirobots Transports Endoscopic Instruments for Minimally‐Invasive Surgery

open access: yesAdvanced Science, EarlyView.
The first electrocautery procedure performed by a team of millirobots (TrainBots) is presented. Enhanced with optimized feet, millirobots form a convoy to facilitate the collaborative transportation of wires and catheters through biological lumens, e.g. bile ducts. It opens up the possibility of using a team of mini‐robots in future endoscopic surgery.

Transformation of 3D Metal–Organic Frameworks into Nanosheets with Enhanced Memristive Behavior for Electronic Data Processing

open access: yesAdvanced Science, EarlyView.
The design of 3D MOFs based on neutral and anionic ligands allows implementing the structural transformation from 3D to 2D nanosheets with improved insulating properties, utilized for efficient ultrathin memristive elements. Abstract The transition from three‐dimensional (3D) to two‐dimensional (2D) semiconducting and insulating materials for micro ...

Analysis of open loop higher harmonic control at high airspeeds on a modern four-bladed articulated rotor [PDF]

open access: yes
The effects of open loop higher harmonic control (HHC) on rotor hub loads, performance, and push rod loads of a Sikorsky S-76 helicopter rotor at high airspeeds (up to 200 knots) and moderate lift (10,000 lbs) were studied analytically.

The calibration and flight test performance of the space shuttle orbiter air data system [PDF]

open access: yes, 1983
The Space Shuttle air data system (ADS) is used by the guidance, navigation and control system (GN&C) to guide the vehicle to a safe landing. In addition, postflight aerodynamic analysis requires a precise knowledge of flight conditions.
