Abstract
An apparatus is provided for detecting fluid low-volume and occlusion in a device using a sensor. One or more force sensing resistors are positioned in communication with a fluid channel at one or more of a pump intake and pump outlet to detect pressure in the fluid channel. The pressure is detected through communication with the force sensing resistor and indicates an irregular system condition including but not limited to, fluid low-volume level and occlusion. Also provided are a fluid flow sensor (e.g., FSR or MEMS sensor) disposed relative to an embedded fluid channel in the base of a wearable medicine delivery pump.
