Abstract In the era of Internet Things, wearable technologies are expected to become an indispensable part daily life. recent times, highly sensitive, flexible, and stretchable electronic gas sensors gaining tremendous interest due their applicability in electronics applications. The construction reviewed for real‐time, selective detection hazardous gases at room temperature (RT) that can be laminated onto a human body or integrated with body‐worn textile other consumer products, utilizing...
The human olfactory system comprises receptor neurons, projection and interneurons that perform remarkably sophisticated functions, including sensing, filtration, memorization, forgetting of chemical stimuli for perception. Developing an artificial can mimic these functions has proved to be challenging. Herein, inspired by the neuronal network inside glomerulus bulb, we present chemosensory synapse sense excitatory inhibitory neurotransmitter release in synapses between interneurons....

Abstract Nanomaterials like graphene and transition metal dichalcogenides are being explored for developing artificial photosensory synapses with low‐power optical plasticity high retention time practical nervous system implementation. However, few studies conducted on Tellurium (Te)‐based nanomaterials due to their direct small bandgaps. This paper reports the superior photo‐synaptic properties of covalently bonded sulfur oxide (TeSO x ) selenium (TeSeO )nanomaterials, which fabricated by...
Abstract Research on transient wearable electronics with stretchable components is of increasing interest because their abilities to conform seamlessly human tissues and, more interestingly, disappear from the environment when disposed. To wear them comfortably, component materials must be pliable, tough, stretchable, biocompatible, and disintegrable. However, most biodegradable are not or limiting use in electronics. Herein, these challenges addressed by demonstrating a nanofiber...
Abstract To create artificial visual perception systems, retina structures that can imitate the behavior of biological in human vision are great interest.
