A Smart Umbrella Design for Enhancing Thermal Comfort in Outdoor Environments

Extreme heat poses a significant threat to human
comfort and health, particularly for individuals who stay
outside for long durations. In this article, the design and
development of a smart umbrella system are proposed, aiming
to enhance personal thermal comfort in hot environments. The
proposed umbrella integrates an active cooling system powered
by a compact-scale control unit. A pelteir module is used here to
convert heat energy into lower and comfortable temperature,
offering a portable and wearable solution to mitigate heat stress.
The system intelligently manages airflow and temperature
within the shaded zone, thereby increasing overall comfort and
usability during hot conditions. The design prioritizes energy
efficiency, usability, and ergonomic factors to ensure versatility
in urban and rural outdoor settings. Field testing validates the
effectiveness of the system for reducing perceived heat,
demonstrating its readiness for use among pedestrians, outdoor
workers, and vulnerable populations. This paper proposes a
sustainable and scalable approach to climate control at a
personal level through wearable smart infrastructure.
