May 6, 2026 /SemiMedia/ —STMicroelectronics has introduced a new range of low-power global shutter image sensors aimed at always-on vision applications in compact, battery-powered devices.
The new VD55G4 and VD65G4 sensors are designed for use in wearables, AR and VR headsets, smart home devices and medical products. They are built to deliver image data while keeping power use low, making them suitable for systems that need to run for long periods on small batteries.
A key feature of the sensors is their ability to monitor a scene continuously at very low power and wake up the main processor only when needed. This event-based approach helps reduce energy use compared with traditional image sensors that run all the time.
The devices are also designed to work easily with low-power microcontrollers and cost-effective system chips, making it simpler to add vision features to small and price-sensitive products. The image data can be used for edge AI tasks, reducing the need to send data to the cloud.
ST said the sensors can use up to ten times less power than typical global shutter sensors, thanks to an optimized design and a dedicated low-power mode. This allows longer battery life and supports use in energy-harvesting systems.
The sensors also come in a small form factor and include basic image processing, helping lower system cost and simplify design for a wide range of consumer and industrial applications.
