Textiles are materials that extensively used in everyday life; textile-based sensors can, therefore, be regarded as ideal devices for a health monitor. However, previously reported textile have limited prospects due to their single function or incompatibility. Traditional generally focus on signal detection, which has not been able combined with an actuator provide real-time status feedback. Thus, date, there no well-established monitoring systems based intelligent textiles. Herein, we...
Abstract As the aging population increases in many countries, electronic skin (e‐skin) for health monitoring has been attracting much attention.
