Functional glasses and wristwatches have already been commercialized as wearable devices are already out in the market. However, the wearers feel unnatural when these devices are used. This unnatural feeling has contributed to the stagnant wearable device market. The ideal wearable device must be worn comfortably and stably. To achieve this, we attempted to realize a functional apparel (e-textiles). Recently, we have developed a wearable sensor in the shape of a Japanese traditional braiding cord, known as a Kumihimo, by weaving piezoelectric poly-L-lactic acid (PLLA) fibers which is one type of chiral polymer (piezoelectric PLLA braided cord). In this study, we introduce the piezoelectric PLLA braided cord developed
