Integrated Hydrophilic Interdigitated Network for Silicone Rubber via a Gradient Polarity Modification Strategy

Advanced Science, EarlyView.
This work overcomes the long‐standing challenge of hydrophilic modification of silicone rubber via a gradient polarity modification strategy. By constructing a hydrophilic interpenetrating network within cured SR, simultaneous surface‐to‐bulk modification is achieved while enabling monitoring through a Eu3+ complex fluorescent tracer.

Heat Transfer in Dielectric Elastomers - Simulating thermal breakdown in multilayered dielectric elastomers

, 2019
Dielectric elastomers are an interesting type of electro-mechanical transducers that can operate both as actuators, generators and sensors. They are composed of an elastomer layer sandwiched between two compliant electrodes and may be arranged in various configurations, including multilayered stacks.

Wireless, Adaptable and Fully Implantable Battery‐powered Devices for Optical Stimulation of the Spinal Cord in Small Rodents

Advanced Science, EarlyView.
Current technologies for spinal cord optogenetic stimulation rely on external power sources and face reliability constraints in freely behaving animals. Here, a fully implantable, battery‐powered optoelectronic device is introduced, enabling operation in any selected environment with wireless recharging for months‐long stimulation.

Thermoelectric Gating Organic Electrochemical Transistors Enabled by Printable Ionogels With n‐p Convertible Thermopower

Advanced Science, EarlyView.
A type of thermoelectric ionogels with convertible n‐p thermopowers are demonstrated with Seebeck coefficients ranging from ‐3.61 to +9.74 mV K−1. Thus, thermoelectric gating organic electrochemical transistor is achieved by employing ionogel as thermoelectric modules and ionic dielectrics simultaneously, paving the road to self‐powered, highly ...

Improved Direct Ink Writing of Liquid Metal Foams via Liquid Additives

Advanced Electronic Materials, EarlyView.
The ability to pattern liquid metal is useful for making soft electrical and thermal devices. Dispensing liquid metal from a nozzle naturally results in the formation of spheroidal droplets, making direct‐write printing challenging. Liquid metal foams containing pockets of air can extrude as filaments, albeit inconsistently.
