Teneray was created to tackle a critical issue: 25% of users abandon their muscle-controlled, myoelectric prosthetic hands because they cannot sense their finger position. Without this feedback, daily tasks feel frustrating and exhausting. Existing solutions involve costly surgical implants or bulky electronics. Teneray is different: it offers a purely mechanical approach to restore sensation. When a finger flexes, cable tension rotates the pulley, causing a small wheel to roll along the hairless, sensitive skin of the lower forearm. With zero electronics, Teneray eliminates hassle with wearing and charging heavy batteries, ensures no feedback latency or noise, and costs under £5 in materials per unit. By providing immediate, intuitive feedback, Teneray improves coordination in everyday tasks, reduces fatigue, and ultimately decreases prosthetic hand abandonment rates.
