HUMAN SURROGATES

Non-Lethal Weapons Surrogate

CFDRC has developed a Non-Lethal Weapons (NLW) Surrogate for the Joint Non-Lethal Weapons Directorate (JNLWD). The surrogate has been designed with modularity as a priority as many of these modalities require unique sensor approaches that would cause uneeded complications in an all-in-one solution. CFDRC is marketing and selling the NLW surrogate based on customer need, meaning the entire surrogate can be purchased with all sensing modalities and instrumentation, or just one. CFDRC has worked closely with Dewetron and offers Data Acquisition Systems that are currently being used with the NLW surrogate. These systems can be sold with use-case set-ups in the Dewetron systems to allow for a true turn-key solution.

The surrogate is capable of measuring a wide range of non-lethal weapon modalities including:

  • Blast (Pressure)
  • Sound (dB)
  • Blunt Impact (Force/Acceleration)
  • Broadband/Laser Light Exposure (mW/cm2, Intensity)
  • Electromuscular Stimulation (Volts/Resistance/Charge Pulse Characterization)
  • RF Heating (Degrees/cm2)
  • Chemical Irritants (Quantification in Air Sample)

The NLW human surrogate is at varying Technology Readiness Levels (TRL). CFDRC is verifying and validiating the Blast, Sound, and Broadband/Laser sensing solutions in the integrated NLW surrogate head. Upon completion of this testing and integration, the NLW surrogate head with those modalities will be made available for purchase and support.

Blast & Sound Surrogate

CFDRC has also developed a blast and sound surrogate head to evaluate helmet protection and injury prevention systems. This surrogate head is designed with sensor locations across the surface of the head to measure pressure loadings under a variety of helmet protection designs. This surrogate also features modular ear inserts which can be outfitted with a wide variety of sound, blast, and other instrumentation based on needs. A rear access panel allows easy access to instrumentation during testing without the need of disassembling the entire surrogate head. Neck fixture attachments can be designed to work with fixed necks or a flexible neck such as the Hybrid III neck. The Blast & Sound Surrogate has been used in both free field explosive testing and repeated shock tube testing to demonstrate robustness and ruggedness. This surrogate also has a virtual component which allows for computational and experimental validation and investigation.

Nasal Cavity Phantoms

Nasal cavity phantoms have been developed as part of a CDC program. They are available for aerosol deposition studies in children of various ages and young adults. Corresponding computational mesh models are available for in silico studies. Phantom models can be customized for specific applications, or we can build entirely new models for you.

  • Based on CT scans of 2,5,7,12,15, and 18 year old children with normal/healthy nasal anatomy
  • High precision, reconstructed from 300-500 CT images per model.
  • Detailed exterior nose, nasal cavity, turbinates, and sinuses (where available).
  • Both left and right nasal cavity are part of phantom (and connected).
  • Exterior nose and face are from skin-like soft material. Ideal for testing/fitting drug delivery devices. Exterior nose and face are available separately.
  • Models are cut at several locations for easy access and cleaning.
  • Available for several ages (2, 5, 7, 12, 15, and 18), other ages on request.
  • Mouth and lung openings can be created in phantoms.
  • Corresponding computational mesh and models are available.
  • Phantom models can be customized for specific applications.
  • Flexible faces are available separately for testing of biomedical devices.
