Heatstroke Prevention Watch

With global temperatures rising and heatwaves becoming more frequent, heat-related illnesses are an escalating public health concern, especially for vulnerable groups like children, the elderly, outdoor workers, and athletes.

This heatstroke prevention watch combines environmental sensors and deep body temperature monitoring to detect early warning signs of heatstroke. It prompts the wearer to take immediate action, such as hydrating or seeking shade. Designed with Renesas' industry-leading low-power technology, the watch enables continuous monitoring and delivers timely alerts through haptic feedback or a built-in speaker. NFC charging and optional Bluetooth^® connectivity enable convenient recharging and mobile integration for broader system use.

System Benefits:

• Ultra-low power MCU enables continuous wear with fast wake-up and extended runtime between charges.
• Single-chip NFC charging simplifies system design, reduces external components, and enables a compact, low BOM design.
• Low-energy flash memory ensures fast reads and auto-interrupts, reducing polling overhead and conserving power.
