Significance Monitoring neuronal activity with cell specificity in freely behaving animal models can yield insights into underpinning operating mechanisms of the brain. Dynamics genetically targeted populations be recorded through calcium indicators; however, current tools for such measurements are only available tethers or large and heavy externalized head stages, potential to influence behaviors test subjects limit experimental paradigms simple two-dimensional arenas. Here, we introduce...
Abstract Implantable deep brain stimulation (DBS) systems are utilized for clinical treatment of diseases such as Parkinson’s disease and chronic pain. However, long-term efficacy DBS is limited, neuroplastic changes associated therapeutic mechanisms not well understood. Fundamental mechanistic investigation, typically accomplished in small animal models, difficult because the need stimulators that currently require either frequent handling test subjects to charge battery-powered or...
Neurotransmitters and neuromodulators mediate communication between neurons other cell types; knowledge of release dynamics is critical to understanding their physiological role in normal pathological brain function. Investigation into transient neurotransmitter has largely been hindered due electrical material requirements for electrochemical stimulation recording. Current systems require complex electronics biasing amplification rely on materials that offer limited sensor selectivity...
Digital medicine, the ability to stream continuous information from body gain insight into health status, manage disease, and predict onset problems, is only gradually developing. Key technological hurdles that slow proliferation of this approach are means by which clinical grade biosignals continuously obtained without frequent user interaction. To overcome these hurdles, solutions in power supply interface strategies maintain high-fidelity readouts chronically critical. This work...
Remote patient monitoring is a critical component of digital medicine, and the COVID-19 pandemic has further highlighted its importance. Wearable sensors aimed at noninvasive extraction transmission high-fidelity physiological data provide an avenue toward at-home diagnostics therapeutics; however, infrastructure requirements for such devices limit their use to areas with well-established connectivity. This accentuates socioeconomic geopolitical gap in health technology points need access...
Abstract Continuous monitoring of electrophysiological biosignals such as electrocardiogram (ECG) and bioimpedance (BioZ) rely on gel‐based electrodes adhesive skin interfaces requiring active patient interaction inherently restricting chronic use. Current solutions aimed at addressing seamless, comfortable, reliable recordings with dry use battery power are limited to days operation clinical‐grade fidelity. Here, current limitations overcome by uniting at‐distance wirelessly powered...
Nicotine, an addictive substance in tobacco products and electronic cigarettes (e-cigs), is recognized for increasing the risk of cardiovascular respiratory disorders. Careful real-time monitoring nicotine exposure critical alleviating potential health impacts not just smokers but also those exposed to second-hand third-hand smoke. Monitoring requires suitable sensing material detect selectively testing under free-living conditions standard environment. Here, we experimentally demonstrate a...
This article demonstrates a 3-D-printed antenna designed for unobtrusive wearable applications operating in the 915 MHz UHF band. The possesses desirable biosymbiotic characteristics to enhance its wearability, including flexibility, stretchability, breathability, and permeability. Specifically, design adopts serpentine meshed configuration construct low-profile planar inverted-F (PIFA). dielectric properties of applied 3-D-printing material corresponding fabrication features are...
