Less Lethal Weapons Testing

Less lethal force is intended to incapacitate or repel targets with a low probability of fatality or permanent injury. A valuable tool for military and law enforcement agencies worldwide, development of these weapons must carefully balance effectiveness with potential injury risk.

Injury severity from impact munitions significantly increases when the skin is penetrated. Safety assessments are critical, and a skin surrogate for penetration evaluations is needed for greater confidence of safety.

Bio-Engineered Skin Surrogate

Luna Labs has developed a physical skin surrogate, TrueTissue, for less lethal weapon evaluations. The material has demonstrated mechanical properties comparable to human skin with less sample-to-sample variability.

Validation Testing Against Human Skin

The assessment of penetration risk for multiple less lethal projectiles has been demonstrated with TrueTissue.
