Recovery Wear 'Miranes' Confirms Changes in Skin Surface Temperature and Blood Flow in Tests Based on Voluntary Standards for Medical Devices
Piquepop Inc., based in Fukuoka, conducted tests to verify the efficacy of the proprietary 'W Far-Infrared Design®' technology in their 'Miranes' recovery wear. Measuring 16 healthy men and women aged 30-60 based on voluntary medical device standards, the results confirmed consistent increases in blood flow and stable skin surface temperature during wear. The company plans to use these findings to support daily conditioning through a scientific approach.

Piquepop Inc. (Headquarters: Fukuoka City, Fukuoka Prefecture; President: Ryosuke Yamanaka), developer of the recovery wear brand 'Miranes,' has conducted tests to verify the efficacy of its proprietary 'W Far-Infrared Design®' technology, which combines highly thermally conductive materials with far-infrared radiating ore prints. The study recorded an increase in blood flow during wear and observed changes in skin surface temperature, referencing voluntary standards for home-use far-infrared blood circulation promoting apparel.
■ Background
With rising health awareness, 'recovery wear' that helps condition the body through wear is gaining attention. Miranes employs 'W Far-Infrared Design®,' integrating specialized heat-conductive fibers and far-infrared radiating ore prints. To evaluate its objective efficacy, human trials were conducted to verify biological responses.
■ Test Overview
Biological responses were tested while wearing the recovery wear featuring 'W Far-Infrared Design®,' referencing the 'Voluntary Standards for Home-Use Far-Infrared Blood Circulation Promoting Apparel' established by the Japan Federation of Medical Devices Associations.
Participants: 16 healthy men and women aged 30-60 who consented to participate and were deemed eligible by a doctor.
Method: Measurements were conducted in a controlled environment (room temperature 24°C, humidity 50-70%) under resting conditions using the following procedure:
- Preliminary measurement at rest before wearing.
- Wearing the 'W Far-Infrared Design®' apparel for 120 minutes, with measurements taken every 20 minutes (total 6 times).
Evaluation Items:
- Blood Flow (μm³/s): Measured in the lower limb artery using a multi-item monitor.
- Skin Temperature (°C): Calculated as the average skin temperature at 7 points across the body using a thermistor thermometer.
■ Test Results
Confirmation of Blood Circulation Promotion (Blood Flow Trends): At all measurement points from 20 to 120 minutes of wear, the results consistently met the '5% or more increase' voluntary standard for medical devices.
Maintenance of Stable Thermal Effect (Skin Temperature Trends): Skin temperature rise was observed from 20 minutes after wearing, and it remained stable in the elevated temperature range throughout the 120-minute measurement period.
*These results were obtained under specific test environments and do not guarantee efficacy in all usage scenarios.
*Results vary by individual.
■ How 'W Far-Infrared Design®' Works
Miranes recovery wear utilizes a unique design combining highly thermally conductive special materials and far-infrared radiating ore prints. This mechanism aims for four effects: 'promoting blood circulation,' 'relieving muscle stiffness,' 'supporting fatigue recovery,' and 'alleviating muscle fatigue,' supporting comfortable daily life.
Based on these test results, it is suggested that Miranes' 'W Far-Infrared Design®' exerts stable thermal effects immediately after wearing and brings sustained blood circulation promotion. The company will utilize these results as insights into product characteristics and continue to aim for a garment that supports daily conditioning through a scientific approach.
