Development of an efficient mid-field wireless power transmission system for biotelemetric IoT medical devices.
Article in Scientific reports, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 4 papers.
What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
Wireless power transfer (WPT) technology facilitates Internet of Things medical devices (IoTMDs) for healthcare monitoring by providing reliable, continuous, and non-invasive power sources. This paper presents an efficient WPT system featuring a flexible receiver ([Formula: see text]) antenna integrated with an efficient rectifier and a flexible transmitter ([Formula: see text]) antenna operating in the midfield band of 1.5 GHz. The implantable [Formula: see text] antenna has a small footprint with a volume of 4.9 [Formula: see text] and can be easily fitted within miniaturized IoTMDs. Extensive simulations and measurement analyses were performed to validate the versatility of the system. The [Formula: see text] antenna exhibited a measured - 10 dB bandwidth of 130 MHz (1.43-1.56 GHz), whereas the rectifier demonstrated a peak measured efficiency of 80% at an input power of 0 dBm. The flexible and conformal nature of the [Formula: see text] facilitates wireless power transmission by enhancing comfort and coupling to nonplanar body surfaces. Remarkably, the system yielded a measured transmission coefficient ([Formula: see text]) of - 22.5 dB at a distance of 51 mm without the use of any additional intermediate structures, such as matching layers, metamaterials, and metasurfaces. For safety reasons, the specific absorption rate was analyzed and confirmed to be within acceptable limits. Furthermore, real-time wireless power transmission capabilities and the potential for operating IoTMDs were demonstrated. In this demonstration, the rectenna's output was used to power an IoT-based temperature sensor-integrated communication module, showcasing the real-time functionality and capability of the proposed WPT system for wirelessly powering IoTMDs.
