Stretchable Tattoo-Like Heater with On-Site Temperature Feedback Control

摘要: Wearable tissue heaters can play many important roles in the medical field. They may be used for heat therapy, perioperative warming and controlled transdermal drug delivery, among other applications. State-of-the-art are too bulky, rigid, or difficult to control able maintain long-term wearability safety. Recently, there has been progress development of stretchable that attached directly skin surface, but they often use expensive materials processes take significant time fabricate. Moreover, lack continuously active, on-site, unobstructive temperature feedback control, which is critical accommodating dynamic temperatures required most We have developed, fabricated tested a cost-effective, large area, ultra-thin ultra-soft tattoo-like heater autonomous proportional-integral-derivative (PID) control. The device comprises aluminum gold resistance detector (RTD) on soft tape as using cost effective “cut-and-paste” method. It noninvasively laminated onto human follow deformation during flexure without imposing any constraint. demonstrate device’s ability target typical uses over extended durations accurately adjust new set point process. low enough justify disposable use.
