Being refreshedWe’re updating our project images and write-ups over the coming weeks.

The finished stimulator: a black box with electrode outputs, a power button and a USB port.

Functional Electrical Stimulator

A multi-channel, computer-controlled electrical stimulation prototype for a research client, built quickly, verified on the oscilloscope and shipped to Vancouver, Canada.

From the bench to Vancouver

  • Oscilloscope screen showing the stimulator’s biphasic output.
  • The stimulator with its electrode pads on a workbench.
  • Bench testing with the oscilloscope and prototype circuits.
  • Inside the prototype: wiring, driver boards and the amplifier.

The brief was to build a multi-channel FES/EMS-style research device, driven from a PC, and to build it fast.

An ESP32 drives an H-bridge and a custom TDA2050A amplifier that delivers biphasic pulses of up to 34 V peak to peak. We verified the output on the oscilloscope and delivered the working prototype to the client in Vancouver, Canada.

This is a research prototype, not a certified medical device.
