Building the world’s highest resolution pressure sensors….
a man that is on a quest will never be depressed.

The sensors have made it to Lindas Norway. Mission almost successful. :).

8 fiberoptic fouling sensors all bundled up and ready to fly with me to Norway. 🇳🇴 .Wish me luck!

This vision would have remained just a vision without the guidance of two remarkable and distinguished mentors: George Eleftheriades and Roman Genov. Thank you both for your unwavering support.

When we connected dots—borrowing from antenna theory here, superoscillation physics there— we found ourselves at the edge of a new frontier in non-invasive neurostimulation. We haven't revolutionized WPT for implantable devices yet, but we've taken that crucial first step.

And it had some exciting implications: we can now steer energy precisely where it's needed, minimizing exposure to surrounding tissue and even powering multiple implants sequentially from a single transmitter.

By incorporating tiny antenna elements within what we call a "Huygens' Box," we programmed surface currents to create focal spots smaller than the wavelength itself, essentially focusing energy into a pinpoint deep under the skin without batteries or wires.

We asked ourselves a wild question: what if we could focus RF fields with surgical precision, deep inside tissue? We took two seemingly distant worlds—superoscillations (the art of beating diffraction limits) and wireless power transfer—and fused them into something entirely new.

My adventure to Red Deer for precision machined Inconel 718 parts was fruitful.

Blew some parts up at 30,000psi in the lab today. Need to get these failures to above 33,000psi by Monday. Wish us luck!

At age 19, I spent a month in the Sahara Desert testing my first electronics project near Tatooine. It actually worked.

Just found out my retinas are fine :). After playing with highish powered lasers for 6 years, I am feeling quite relieved.

The new cleanroom is finished!! They let me inside. This is a 20 second tour.

Data scientists keen.Poor data so mean.Their insights stay lean.

Can anyone help me with a short rhyme or poem that makes fun of data science teams trying to bring value to a company but using poor sensor data?

It was a good day for disco dicing. No broken blades and perfect rectangular parts :).

I love it when people who know take time out of their day to explain to me how electrons feel.
@Chrismholt @mccartydan he feels the gentle breeze from the shaking field, shivering electrons up and down his spine, and sending some weak fields back out (he is lying on the ground).(maybe ill export some gif of the shaking field later.
