Amplifying Touch Using 3D ZnO Tetrapods for Tactile and Haptic Intelligence.
Article in Small (Weinheim an der Bergstrasse, Germany), 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 3 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
Advances in tactile and haptic intelligence are driven by development of advanced funtional materials capable of translating subtle physical interactions into precise electrical signals. This study presents an innovative approach to enhancing touch sensitivity by incorporating 3D Zinc Oxide (ZnO) tetrapods into a piezoelectric polymer matrix. The distinctive 3D architecture of the ZnO tetrapods significantly improves the mechanical-to-electrical conversion efficiency, thereby amplifying the material's ability to detect fine tactile forces. We optimized the loading of ZnO tetrapods within a Polyvinylidene fluoride (PVDF) matrix, resulting in a highly responsive composite material for tactile sensing. It exhibited exceptional performance in detecting minute pressure variations, with just 4 wt.% tetrapods in the polymer matrix. Output voltage and current of the composite matrix increased from 4 V, 0.5µA to 19 V, 2.5µA respectively when the concentration of the ZnO tetrapods is gradually increased from 0-4 wt.% and decreased with further increase in tetrapod concentration. Comprehensive analysis and applications of this piezoelectrical materialconfirmed its robustness across a range of pressure conditions. The amplification of touch sensitivity and signal responsiveness underscores the potential of 3D ZnO tetrapods for tactile and haptic technologies.
