Raw Description
Product | Our sensor fabrication process utilizes a proprietary technique called flame brush pyrolysis (FBP). The metal precursor is sprayed upon gold interdigitated electrodes via FBP to form a sensor. FBP can produce nanoparticles as small as 15nm. When a population of nanoparticles are sprayed upon a substrate, they form a porous structure which has a high surface area. It allows gas to enter and leave easily making the sensor highly sensitive and responsive. Then the sensor is required to be packaged in a proprietary sensor suspension packaging in order to be used with other devices as a module. | The sensing mechanism utilizes the characteristic of an n-type semiconductor i.e. tungsten oxide to form a layer of adsorbed oxygen ion to react with target gas. When tungsten oxide encounter ketone gas a redox reaction would happen to give an electrical signal. | Technology | Our sensor fabrication process utilizes a proprietary technique called flame brush pyrolysis (FBP).

Current technologies in ketone sensing are either invasive or offer ketone sensing with low sensitivity in the concentration range of 1mg ketone bodies per liter air (ppm) and low specificity. Our semiconductor ketone gas sensor provides ketone sensing capability in the range of part per billion range which is over 1000X more sensitive. Imagine a person starts to run on a treadmill hoping to lose fat, while human breath contains 200ppb of ketone bodies at rest when a person starts to burn more fat the breath ketone concentration would increase. Only our sensor could indicate improving fat burning rate. A person seeing an instant positive results is a motivated person.

Strategic Analysis

Executive Brief

King's Phase Technologies specializes in high-sensitivity gas sensing, specifically targeting breath ketone detection for health and medical applications (fat loss and ketoacidosis). Their core technology utilizes Flame Brush Pyrolysis (FBP) to deposit nano-porous tungsten oxide (WO3) onto gold interdigitated electrodes, achieving part-per-billion (ppb) sensitivity. They are currently scaling their proprietary "sensor suspension packaging" for modular device integration.

Strategic Fit & Lead Score

Lead Score: 68 (Adjacent Tech / High-Performance Sensing)

Why this Score? While King's Phase currently uses metal-oxide semiconductors (WO3), their push for ppb-level sensitivity and high specificity puts them in a performance bracket where traditional substrates and electrodes reach their physical limits. Diamond technology offers two critical upgrades for them:

  1. Thermal Stability: Metal-oxide sensors often require precise micro-heating to optimize gas redox reactions.
  2. Electrochemical Superiority: Boron Doped Diamond (BDD) is the world's most stable and sensitive electrode material, offering a potential next-generation path beyond gold-based interdigitated electrodes for even higher specificity.

6C Solutions Proposal

Application Area 6C Solution Technical Value Prop
Thermal Substrates PCD (Polycrystalline) Wafers Metal-oxide sensors (WO3) often operate better at elevated, stable temperatures. PCD diamond substrates provide the world's highest thermal conductivity, ensuring zero thermal gradients across the nano-porous structure, leading to more consistent electrical signals.
Electrode Evolution BDD (Boron Doped Diamond) Coatings Transitioning from gold to BDD electrodes can eliminate electrode "poisoning" and baseline drift. BDD has a wide electrochemical window and is chemically inert, preventing the substrate from reacting with the ketone gases or moisture in human breath.
Stability & Barrier Ultra-Thin SCD/PCD Capping Applying a nano-scale diamond "mesh" or coating via MPCVD can protect the 15nm nanoparticles from sintering or mechanical degradation without blocking gas permeability, significantly extending sensor lifespan.
In-house R&D Custom MPCVD Reactor As King's Phase scales, owning an MPCVD system allows them to experiment with Diamond-on-Semiconductor architectures, creating a hybrid WO3-on-Diamond sensor that outperforms current silicon-based benchmarks.

Engagement Hooks

  • Technical Question: "Your FBP process achieves incredible 15nm nanoparticle porosity. Have you encountered baseline drift or sensitivity loss due to thermal gradients across the gold electrodes during the redox reaction, and could a high-conductivity PCD substrate stabilize that signal-to-noise ratio?"
  • Value Statement: "6C can help King's Phase move from ppb to ppt (part-per-trillion) sensitivity by replacing traditional electrode materials with Boron Doped Diamond, the most chemically stable and sensitive sensing surface known to material science."
