Concept wearable system aims to regulate body core temperature in extreme climates

SINGAPORE, 9 March 2026: The developer of a concept wearable technology called InfernoCool Underguard said the system has been designed as a device-based undergarment intended to regulate body core temperature in both extreme cold and extreme heat.

Making the announcement through a Press Release, the inventor said the concept emerged from the observation that traditional thermal protection has historically focused on external clothing, beginning with early insulation methods such as animal fur and skin and evolving into modern thermal garments. The inventor said the concept behind InfernoCool Underguard explores the possibility of integrating climate-control technology directly into a wearable undergarment to protect the body’s core.

The developer said the concept for the system was first envisioned around a decade ago as a device-based garment capable of adjusting temperature through a mobile application and added that work to develop the idea began in mid-2025, when the concept was formally introduced under the name InfernoCool Underguard.

The inventor said the proposed system incorporates graphene heating films and a two-tier cooling mechanism within a layered wearable structure. The inventor said the concept is designed to address scenarios involving extreme climates, noting that users could potentially regulate their body temperature in cold environments or lower the microclimate temperature within the garment in hot conditions.

The inventor said the project is currently at an early development stage and has been assessed for potential prototyping. The developer added that Enterprise Singapore highlighted the need for funding support, while A*STAR Singapore indicated readiness to assist with prototype scoping. The inventor added that AJ Protech in the United States reviewed the concept and estimated that prototyping could be achieved at a cost of approximately USD 76,000.

The developer said legal advisors, Amica Law LLC and Mark Clerk Singapore LLC, recommended filing a patent application due to the novelty of the concept, adding that a patent filing has already been completed in Singapore.

The inventor said the garment is intended for use in a wide range of environments and professions where individuals may be exposed to extreme temperatures, with potential applications including personnel in sectors such as emergency services, industrial work, construction and outdoor activities, as well as individuals seeking temperature regulation during everyday activities.

The inventor said the concept is currently presented at a preliminary stage and that collaboration and funding partners are being sought to support further development and prototyping of the technology.
