Wearable Music Tuning Ring for the Concert Pitch Using PVDF/BCZT Piezoelectric Composites.
Article in Polymers, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
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
Instrument tuning is crucial for the performance quality of orchestral concerts. In most cases, the standard pitch is usually given by the oboist, and then the rest of the orchestra adjusts their instruments to match it. However, in the individual training scene, music instrument players often rely on a piano or a pitch pipe for the standard pitch. The piano is not portable, and the pitch pipe could be inaccurate. Therefore, a portable, accurate and user-friendly tuning device is urgently required. In this work, we sought to design a wearable music ring using high-performance PVDF/BCZT composites to stimulate the standard pitch when needed anywhere and anytime. In the music ring, there are two core buttons that stimulate and modulate the output voltage and create the standard pitch. To optimize the performance, we constructed a composite structure, with BCZT particles embedded in highly oriented polyvinylidene fluoride (PVDF) fibers. The composite presents an aligned fiber structure, which endows it with high piezoelectricity. It presents sensitivity as high as 0.12 V N
