The problem

Turn small signals into a portable instrument.

The system had to acquire small differential signals across multiple channels within a mechanical load. The challenge was to reproduce an existing laboratory measurement setup in a compact standalone device that could operate from a battery and record results over time.

That introduced multichannel acquisition, local storage, timestamping, wireless communication, charging and enclosure constraints alongside the precision analog measurement problem.

Role

  • Electronic system and precision measurement architecture.
  • ADC and analog-interface design.
  • Schematic development, PCB design and component selection.
  • Battery-operation and charging integration.
  • BLE, RTC and microSD hardware integration.
  • Production documentation and commercial-enclosure selection.

Engineering challenge

Measurement performance depends on the complete system.

Resolving small differential signals across multiple channels

Constraint

Small signals had to be acquired reliably as part of a compact, battery-powered instrument.

Engineering approach

The design considered measurement topology, reference, input conditioning, ADC architecture and PCB implementation together. Battery power, charging, logging, wireless transfer and enclosure fit were integrated into the same architecture rather than added after the analog front end.

Result

The resulting electronic architecture combines precision multichannel acquisition with autonomous power, data logging and Bluetooth connectivity in a compact form factor.

Outcome

Electronic architecture and production-ready PCB design.

The project produced the electronic architecture and PCB design for the ENSYS portable precision measurement instrument, integrating low-level signal acquisition with battery power, local data logging and wireless connectivity. Validated measurement accuracy and final prototype performance are not claimed here because those results are not part of the available public documentation.
