The Invisible Signals That Make Innovation Possible

Some of the world’s biggest breakthroughs start with something incredibly small — an electrical signal so tiny it seems invisible. At Tolicore, we build instruments that detect these signals, allowing researchers and engineers to measure electrical currents down to femtoamperes — that’s 1 x 10-15 ampere! For context, that’s a millionth of a billionth of an ampere! It might sound abstract, but in the right hands, that level of sensitivity can change how we live.
That’s the magic of what we do: we make it possible to see the unseen.
In labs and factories, engineers use our instruments to find tiny electrical problems that might otherwise go unnoticed. By catching these invisible issues early, they can prevent devices from failing and make electronics safer and more reliable — whether it’s a new gadget, a scientific instrument, or a medical device under development.
This kind of precision also supports innovation in semiconductors, biomedical, and other R&D fields. By knowing exactly how currents behave at the smallest scales, researchers can improve performance, reliability, and efficiency, laying the foundation for the next generation of technology.
I joined Tolicore because I’ve always been fascinated by the idea that real progress often starts with something invisible. Our founder, Anatoly Shtykov, built Tolicore on decades of experience in optoelectronics and semiconductor systems. His goal was simple: to give researchers and engineers a tool they could truly trust when every fraction of a measurement matters.
Working alongside our customers, I’ve seen firsthand how much innovation depends on precision. Every discovery begins with someone carefully measuring and understanding what others can’t yet see.
That’s why our instruments are built not just for accuracy, but for reliability and convenience. Designed for engineers, by engineers, they’re compact, portable, and intuitive, making it easier to get precise measurements without overly complicated setups. They’re used in labs where even the smallest noise or drift could distort an entire experiment. We help make sure that what’s being measured is real — and that the data can stand up to the biggest challenges.
When I think about the future, I see technology becoming more sensitive, more integrated, and more human. Devices will monitor our health noninvasively, computers will waste less energy, and new materials will make renewable energy more efficient. And somewhere, quietly behind all of that, our instruments will be measuring the tiny signals that make it all possible.
At Tolicore, we believe that the smallest measurements often enable the biggest breakthroughs, and that’s where the real progress begins.
