32-bit MCU powers eye therapy device

It is powered by an STM32WB55 dual-core Bluetooth LE (BLE) microcontroller (MCU).

Nu Eyne’s recently launched CELLENA wearable device utilizes electric current and light emitted to the eyes and associated nerves to relieve eye dryness and fatigue, as well as to promote healthy retinal functions.

Durable and light for everyday use, the device supports multiple therapy sessions on a single charging cycle and records and stores product-usage logs.

A mobile application will be released soon for greater user convenience and interactive therapy management.

The CELLENA device relies on the dual-core architecture of the STM32WB55 MCU for reliable wireless connectivity and real-time processing.

With its embedded security features, ST’s MCU also delivers multiple security mechanisms, including user data protection and encrypted firmware update over BLE.

The STM32WB55’s ultra-low-power performance also significantly extends battery runtime of Nu Eyne’s wearable eye-therapy.

“The wireless performance of the STM32WB55 MCU inside CELLENA exceeded our expectations and made it easier to focus on our primary objective of delivering a product to promote tissue regeneration and relieve dry eyes and pain,“ said Joowan Seo, Director of Technology and Engineering, Nu Eyne. “All Nu Eyne products are powered by MCUs from ST, which enables us to promptly integrate new STM32 chips in our designs using the easy-to-use STM32 development software. We have chosen ST for their consistent and reliable high-quality products and technical support. ST actively engages with their partners to find solutions from the early stages of development.”

“Nu Eyne’s decision to rely on STM32 wireless MCUs for their innovative wearable eye-therapy device is a perfect example of our life.augmented mission to use technology to make a positive contribution to people’s lives,” said Arnaud Julienne, Vice President, Head of Marketing and Applications of MDG, IoT/AI Competence Center and Digital Marketing, Asia Pacific Region, STMicroelectronics. “This collaboration with Nu Eyne demonstrates the tremendous potential of STM32WB MCUs for the healthcare market, where security, together with high performance and low power, is essential.”
