I've got a feeling Sensory (or afferent) nerves bring sensations of touch, pain, or temperature variation to the central nervous system and brain. Using tools materials organic electronics, Kim et al. combined pressure sensor, ring oscillator, an ion gel–gated transistor form artificial mechanoreceptor (see Perspective by Bartolozzi). The combination allows for sensing multiple inputs, which can be converted into sensor signal used drive motion cockroach leg in oscillatory pattern. Science ,...
Abstract Solid‐state electrolyte materials are attractive options for meeting the safety and performance needs of advanced lithium‐based rechargeable battery technologies because their improved mechanical thermal stability compared to liquid electrolytes. However, there is typically a tradeoff between electrochemical performance. Here an elastic Li‐ion conductor with dual covalent dynamic hydrogen bonding crosslinks described provide high resilience without sacrificing room‐temperature ionic...

With advances in electronic-skin and wearable technologies, it is possible to continuously measure stress markers from the skin sweat monitor improve wellbeing health. Understandably, sensor's engineering resolution are important towards its function. However, we find that people looking for an e-skin sensor may look beyond measurement precision, demanding a private stealth design reduce, example, social stigmatization. We introduce idea of sensing "wear index," created combination...
Surface plasmon resonance (SPR) sensing is one of the most widely used methods to implement biosensing due its sensitivity and capacity for label-free detection. Whilst commercial SPR sensors operate in angular regime, it has recently been shown that an increase a greater robustness against noise can be achieved by measuring reflectivity when varying both angle wavelength simultaneously, so-called spectro-angular biosensor. A single value decomposition method project two-dimensional...
Poly(dimethylsiloxane) (PDMS) microstructures have been widely used in bio-microelectromechanical systems (bio-MEMS) for various types of analytical, diagnostic and therapeutic applications. However, PDMS-based soft lithographic techniques still use conventional microfabrication processes to generate a master mold, which requires access clean room facilities costly equipment. With the increasing these fields, development benchtop fabricating microdevices is emerging as an important challenge...
Abstract Chronic stress has been associated with a variety of pathophysiological risks including developing mental illness. Conversely, appropriate management, can be used to foster wellness proactively. Yet, there is no existing method that accurately and objectively monitors stress. With recent advances in electronic-skin (e-skin) wearable technologies, it possible design devices continuously measure physiological parameters linked chronic other health conditions. However, the approach...
Abstract Due to relatively low charge‐carrier mobilities in organic materials, high operational voltages often have be applied and result severe limitations. While it has been reported that elastic polymeric dielectrics, containing a very ion concentration, are able overcome this bottleneck, systematic study on the working mechanisms their implications for sensors is still missing. possibility form double‐layer capacitor while maintaining insulating properties, such dielectrics enable stable...
