Overcoming size constraints, power consumption, and signal noise to deliver medical-grade data accuracy in ultra-small wearable devices.

A custom closed-loop automated air pump control system featuring 5ml/min precision, adjustable 1-8L/min flow, and integrated PC software for advanced research applications.

Background: A prominent university materials science laboratory possessed a highly accurate, yet outdated spectrometer. While mechanically and optically sound, its control interface was restricted to a legacy DOS-based system, requiring manual data extraction via floppy disks. Our Solution: Our engineering team developed a custom bridging PCB utilizing an ARM Cortex-M4 microcontroller. This board intercepted the…

The Challenge: Designing a custom data acquisition (DAQ) board capable of sampling at 5 K/s while maintaining an ultra-low noise floor for mechanics research. Engineering Approach: We utilized a 10-layer PCB stack-up with Rogers RO4350B high-frequency laminate. Critical high-speed traces were routed as strictly impedance-controlled differential pairs with via-stitching to suppress EMI. Power delivery networks…

The Transition: Moving from a messy breadboard or functional lab prototype to a product that can be manufactured at scale is a daunting task for many research teams. DFM Strategies: We work closely with our clients to implement Design for Manufacturing (DFM) and Design for Testing (DFT) principles early on. This includes minimizing the BOM…
