Abstract

Purpose

This study aimed to investigate the effects a cushion has on electrophysiological signals and to identify the important design elements required for manufacturing better therapy cushions.

Design/methodology/approach

Four types of attachment cushions were manufactured by changing the shell fiber (cotton or microfiber) and the interlining (synthetic loose fiber or buckwheat). The products were evaluated by 20 healthy individuals (10 stable cushions and 10 unstable cushions). We examined the participants by electroencephalography (EEG) and electrocardiography (ECG).

Findings

The authors found significant differences in both EEG and ECG between participants with unstable and stable attachment types.

Originality/value

A complex approach to emotional product evaluation was attempted by analyzing differences due to design variables of cushions through subjective evaluation as well as EEG and ECG.

Abstract

Purpose

This study aims to provide information on how to monitor the temperature setting of a heating device in order to implement a heating unit successfully in the smart clothing by observing voluntary heating behavior of wearers.

Design/methodology/approach

Subjects wearing base layers and additional clothing were asked to turn on and off the switch when wanted in the cold environmental chamber. Tolerable range of skin temperature (TST) depending on the location of body was obtained by observing the temperature at the time when the heating device was turned on and off during a rest–running–rest protocol.

Findings

The TST was 32.8–49.4 °C and decreased to 31.3–37.6 °C around abdomen and back waist, respectively. Changes in the wearers' voluntary control behavior were observed depending on the individual's level of cold-sensitivity and activity level of rest and running. TST was 35.8–49.4 °C (Rest 1: rest before exercise), 40.0–42.0 °C (Running) and 35.3–43.2 °C (Rest 2: rest after exercise) for cold-sensitive group, whereas it was 32.8–36.2 °C (Running) and 34.4–45.7 °C (Rest 2: rest after exercise) for cold-insensitive group.

Originality/value

In this study, results with detailed body locations and wearer's thermal sensitivity provide practical references for the implementation of a heating device to the comfortable multilayered smart clothing.
