Bare finger tactile sensing for edge orientation and contact position using excitation from fingernail.
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 1 paper.
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
In recording and reproducing skills involving the fingertips, a sensor that measures tactile information of fingertips is important. However, when the sensor covers the finger pad, the inherent sense of touch is compromised. We introduce a new tactile sensor, a pair of a vibration motor and a 6 degrees-of-freedom sensor attached to a fingernail that enables tactile sensing without covering the fingertip. This sensor estimates finger contact information by measuring vibrations caused by an eccentric motor positioned on the fingernail. The time series of the acquired angular velocity and acceleration data were utilized to identify the edge orientation and the contact position of the touching object. The results of the conducted experiments indicated that this setup can simultaneously identify both the edge orientation and the contact position with an accuracy of 71.67%. Potential applications include remote tactile transmission, integration with a robotic finger, and the detection of grasping postures in real objects.
