Class II Biometric Wearable: High-Density ECG Patient Monitor

The Problem

A medical technology startup required a low-profile continuous ECG diagnostic patch. The existing client design was bulky, prone to high analog signal noise interference, and depleted its battery in under 72 hours.

The Solution

We engineered a rigid-flex 4-layer PCB with decoupled ground layers to isolate the AD8232 analog front-end from high-frequency BLE noise. By using fine-pitch BGA components and advanced power sleep profiles, we minimized layout area.

Precision Farming: LoRa Telemetry Node Network

The Problem

Agritech networks fail due to signal absorption in dense leaf canopies and severe physical deterioration in high-moisture farm soil.

The Solution

We tuned custom 433MHz microstrip line antennas on 2-layer FR4 boards. The hardware was integrated into an IP68-rated polyurethane-potted enclosure, fueled by a high-efficiency solar harvesting circuit with LiFePO4 battery regulation.

Electric Vehicles: GaN Active-Balancing Battery Management

The Problem

Traditional passive shunt battery balancers suffer massive heat generation during 100A charging peaks, causing dangerous heat spikes inside tightly packed battery compartments.

The Solution

We developed an active battery balancing module using high-frequency Gallium Nitride (GaN) switching circuits. By employing 2oz heavy copper pours and thermal vias linked to mechanical chassis heat-sync pads, heat was dissipated evenly.
