Wireless, implantable catheter-type oximeter designed for cardiac oxygen saturation.

KunHyuck Lee, Hao Zhang, Kyeongha Kwon, Xue Feng et autres

Accurate, real-time monitoring of intravascular oxygen levels is important in tracking the cardiopulmonary health of patients after cardiothoracic surgery. Existing technologies use intravascular placement of glass fiber-optic catheters that pose risks of blood vessel damage, thrombosis, and infection. In addition, physical tethers …

Bioresorbable, wireless, and battery-free system for electrotherapy and impedance sensing at wound sites

Mirae Kim, Wei Lu, Kyeongha Kwon, Yugang Liu et autres

Chronic wounds, particularly those associated with diabetes mellitus, represent a growing threat to public health, with additional notable economic impacts. Inflammation associated with these wounds leads to abnormalities in endogenous electrical signals that impede the migration of keratinocytes needed to support the …

Multiwavelength Implantable Oximeter for Wireless Monitoring of Tissue Oxygenation in the Presence of Blood Volume Changes

Anat Usatinsky, Hugo L. Higueros‐Garcia, Sadi Loai, Samantha Unger et autres

ABSTRACT Real‐time continuous measurement of tissue oxygenation (StO 2 ) can provide insight into organ transplant health and disease progression and provide feedback after medical interventions. However, existing optical oximetry approaches typically assume stable blood volume, limiting their usefulness in real‐world scenarios …

Safe, high-performance, moisture-activated batteries for powering next-generation Internet-of-Things devices

Veena Misra, Gurudatt N G, Bhavya Jain, Pei Liu et autres

Conventional batteries are heavy, nonconformal, and toxic, while energy harvesters offer low/variable power, rendering them unsuitable for emerging wearable, robotic, and other Internet-of-Things (IoT) devices. Here, we introduce a nontoxic, thin-film battery superior to several commercial batteries inspired by advances in water …

Smartphone-Based Immune Response Measurement Using a Colorimetric Self-Assembled Plasmonic Biosensor

Mahdi Soudi, Ángel David Torres Palencia, C.D. Beech, Pablo Cencillo‐Abad et autres

We present a point-of-care, cost-effective colorimetric nanosensor that leverages gap-plasmon dispersion of self-assembled aluminum nanoparticles on a phase-matched near-field cavity for antibody Immunoglobulin G (IgG) detection. The sensor achieves a broad dynamic range of 10 μg/mL to 5 mg/mL with a limit …

Adaptive electronics for photovoltaic, photoluminescent and photometric methods in power harvesting for wireless wearable sensors

Chanho Park, Do Yun Park, Haohui Zhang, Da Som Yang et autres

The increasing demand for continuous, comprehensive physiological information captured by skin-interfaced wireless sensors is hindered by their relatively high-power consumption and the associated patient discomfort that can follow from the use of high capacity batteries. This paper presents an adaptive electronics platform …

Optogenetic activation of the gut-brain axis in freely moving mice using a fully implantable wireless battery-free device

Timothy J. Hibberd, A.Yu. Efimov, Yue Wang, Mingzheng Wu et autres

The findings demonstrate that distinct behavioral changes can be induced by wireless activation of the terminal region of the large intestine (distal colon and rectum) in freely moving rodents, using fully implantable battery-free devices.
