Tri-Band Scalar

Triple-band scalar output runs three separate scalar signal layers from a microprocessor-controlled device, generating a coherent field based on non-repeating, nature-based patterns like phi ratios and Fibonacci sequences, so the body can tune into it rather than block it out. It's the standard output across the Phi, Sensitive, and Ultimate ranges.

Alpha, Beta Frequencies

Alpha waves maintain a relaxed, calm mental state to filter out sensory distractions, while beta waves shift the brain into active concentration, logical thinking, and alert problem-solving.

Backed by Research

Blushield is the only device in its category backed by a peer-reviewed human pilot study (PubMed ID: 39355415, 2025). The study measured real people in real environments and reported improvements in heart rate variability, sleep quality, cognitive function, and blood glucose regulation.

Set Up

Choose a location — Position the C1 in a central area of the space you want protected, close to a power outlet and away from damp or water.
Plug it in and leave it running — Connect the 12V power pack and switch on. The field activates immediately, no app, no pairing, no settings, and it runs continuously. Allow up to two weeks for your body to fully adjust.
Pair for full coverage — The C1 covers up to 320m². Add an Ultimate Portable or Ultimate Watch for protection when you're outside your primary zone.

What to Expect

Give the device at least two weeks of continuous use before judging the results. Some people experience a short adjustment period in the first few days, in keeping with the Alpha and Beta waveforms it's tuned to for alert, focused energy. Sleep is usually the first thing to settle, with a noticeable difference for most within two to four weeks.

The evidence

25 people. 12 weeks. Their own homes.

Participants used Blushield in their own homes while a range of health markers were tracked. They recorded improvements across sleep, heart rate variability and cognitive performance, with no adverse events reported. The study was single-arm, with no comparison group (D'Adamo et al., 2024, n=25).

Read the full study

Deeper sleep

Sleep duration increased (P < 0.04), alongside measurable changes in resting heart rate and body temperature.

Improved HRV

Heart rate variability improved (P < 0.04). HRV is a measure of nervous system adaptability and recovery capacity.

Improved cognition

Cognitive performance improved across composite memory, cognitive flexibility, executive function and processing speed (P < 0.02).

Safe

No adverse events were reported, with 100% participant compliance across the 12 weeks.

Sleep has transformed for the whole household. The pyramid looks beautiful on the sideboard too — it doesn't look like tech.

Upgraded from the Cube and the difference in a larger home is noticeable. Worth the investment for whole-home cover.

Plugged it in and forgot about it — exactly what I wanted. Felt calmer within the first week.
