Liquid Metal Embedded Elastormers

Redefining fundamental trade-offs

LMEE breaks the fundamental trade-off between elasticity and thermal conductivity, opening up a whole new range of material possibilities.

Arieca is a product of over 10 years of academic research by our co-founders, Dr. Majidi and Dr. Kazem, and a talented team of researchers at Dr. Majidi’s Soft Machine’s lab at Carnegie Mellon University (, supported by over $4M research grants from NASA, AFRL and NSF.

The result is a breakthrough multi-functional LMEE composite material that breaks the long-standing trade off that high thermal and electrical functionality is achievable only in stiff, brittle and inflexible material.
