Abstract

fetched live from OpenAlex

Upper limb amputations severely impact individuals' quality of life, affecting physical functioning, mobility, and proprioception. Traditional and affordable prosthetic devices often lack sensory feedback, leading to difficulties in use and prosthesis rejection. This article explores the development of a power-autonomous, solid-state haptic feedback prosthetic system based on dielectric elastomers (DEs). The soft devices detect mechanical pressure and convert the signal into actuator vibration, delivered to existing, innervated anatomical parts that relay the signal to the user's brain. Integrating capacitive DE-based pressure sensors with DEA-based vibrotactile armbands offers a potential solution to restore sensory feedback, enabling users to perceive touch and regain enhanced perception of the environment. The proposed system addresses challenges in energy consumption and device autonomy. Detailed fabrication methods are provided for the actuators, sensors and the power autonomous integration system that enables joint operation. Characterization studies demonstrate the system's effectiveness, and a user study confirms its potential for frequency discrimination and strength perception. This innovative approach using DE-based technology presents a promising avenue for enhancing upper limb prosthetics and improving the quality of life for amputees.

Full frame distilled prediction

Teacher imitation

Not calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model labels.

Machine scores (provisional)

The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.

Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
