Abstract
Continuous microfluidic dilatometry devices and methods are provided for activity monitoring with ultra-high sensitivity. Corner flow in capillary channels is used to detect the resistance change in microfluidic circuits filled with ionic liquids. The conversion of mechanical input (e.g. strain) to an intermediary domain, namely liquid displacement, allows a large enhancement in sensor performance. Embodiments are suitable for tracking skin deformations that occur as a result of human movements.
