Abstract:We present a wearable microfluidic impedance cytometer implemented on a flexible circuit wristband with on-line smartphone readout for portable biomarker counting and analysis. The platform contains a standard polydimethylsiloxane (PDMS) microfluidic channel integrated on a wristband, and the circuitry on the wristband is composed of a custom analog lock-in amplification system, a microcontroller with an 8-bit analog-to-digital converter (ADC), and a Bluetooth module wirelessly paired with a smartphone. The l… Show more
“…58 Moreover, the device is simple from the microfabrication point of view, because it is based on a coplanar-electrode layout, and it is easy to operate, because no focusing mechanisms are required. Therefore, when coupled with a fully integrated electronics, 59,60 it has the potential for pointof-care testing applications.…”

“…It must be noted that merely changing the substrate from PCB and mounting the same rigid ICs on the flexible PCB does not make it flexible for the desired application. Moreover, many presented flexible systems have flexible sensory parts but the core of the readout circuit is a microcontroller or data acquisition system that in itself is not flexible, also, the sensory platforms are not stand‐alone . Most often, these flexible sensors are connected to the data acquisition system by either wire‐bonding or soldering wired connectors that again make the system vulnerable for failure.…”

“…Moreover, many presented flexible systems have flexible sensory parts but the core of the readout circuit is a microcontroller or data acquisition system that in itself is not flexible, also, the sensory platforms are not stand-alone. [39][40][41] Most often, these flexible sensors are connected to the data acquisition system by either wire-bonding or soldering wired connectors that again make the system vulnerable for failure. Hence, a practical approach toward obtaining a fully compliant system needs absolutely no rigid components.…”
Advances in marine research to understand environmental change and its effect on marine ecosystems rely on gathering data on species physiology, their habitat, and their mobility patterns using heavy and invasive biologgers and sensory telemetric networks. In the past, a lightweight (6 g) compliant environmental monitoring system: Marine Skin was demonstrated. In this paper, an enhanced version of that skin with improved functionalities (500–1500% enhanced sensitivity), packaging, and most importantly its endurance at a depth of 2 km in the highly saline Red Sea water for four consecutive weeks is reported. A unique noninvasive approach for attachment of the sensor by designing a wearable, stretchable jacket (bracelet) that can adhere to any species irrespective of their skin type is also illustrated. The wearable featherlight (<0.5 g in air, 3 g with jacket) gadget is deployed on Barramundi, Seabream, and common goldfish to demonstrate the noninvasive and effective attachment strategy on different species of variable sizes which does not hinder the animals' natural movement or behavior.
