India, Feb. 21 -- Researchers at University of California San Diego (UC San Diego) and CEA-Leti have unveiled a groundbreaking microactuator driving system, combining innovative solid-state battery technology with novel integrated circuit designs for 2-in-1 storage and voltage boost conversion techniques.

Presented in a paper at ISSCC 2025, "An Autonomous and Lightweight Microactuator Driving System Using Flying Solid-State Batteries", the breakthrough addresses a critical challenge in powering micro-actuators: delivering high voltages (tens to hundreds of volts) efficiently in a lightweight, compact form.

By dividing a solid-state battery - which is already needed in the system - into smaller units and dynamically arranging them, the s...
