Engineers at UC San Diego built a smart ring prototype that reads glucose, lactate, and electrolytes directly from fingertip sweat pores without needles. The biochemical micro-sensors replace standard optical trackers with real metabolic data, though packaging the tech into retail jewelry remains years away.
Makers are bypassing bloated AI pins and screen distractions by turning back to tactile hardware. JeanDeBaill built the Claude Pager, an ESP32-powered pocket device that converts spoken prompts into instant text on a 2.9-inch e-paper display. It delivers multi-day battery life and silent answers without phone notifications or rambling voice assistants.
Wearers are stripping the straps off Google's screenless tracker and taping the sensor pod directly to their biceps or chest with athletic tape. The DIY setup frees wrist space for classic mechanical watches while capturing more accurate biometric data during intense workouts.
