Arieca Announces an Agreement to Develop a Liquid-Metal-Based Thermal Interface Material for Power Modules in the Electric Vehicle (xEV) Segment

(Pittsburgh, PA.) Arieca, a leader in liquid-metal-based Thermal Interface Materials (TIM), entered into a joint research agreement with ROHM Co., Ltd., a leading provider of power semiconductor devices for the xEV market, to develop next-generation TIM using Arieca’s Liquid Metal Embedded Elastomer (LMEE) Technology. This joint research leverages the LMEE platform to provide high heat transfer without the reliability issues facing conventional TIM technologies.

“ROHM is a global leader in SiC power module technology,” Navid Kazem, Arieca’s CEO said. “Their SiC devices can significantly improve power delivery in xEV while reducing the size of power inverters. Arieca is excited to partner with such an innovative company to improve the performance of power module assembly in the xEV market.”

“We need an innovative thermal interface material between the power module and heat sink,” said Ken Nakahara, Fellow and Head of ROHM’s R&D Center. “The most important requirement is compatibility with sufficient thermal conductivity and reliability, which are usually in a trade-off relationship. Arieca’s LMEE has the possibility to satisfy this prerequisite, allowing us to innovate in the xEV market. As a result, we decided to start collaborative R&D with Arieca. “This joint research agreement provides ROHM with the latest TIM technologies required to successfully introduce next-generation SiC power modules for xEV applications.”

NBMC/AFRL News Press Release

Arieca Receives a grant from the Nano Bio-Materials Consortium (NBMC) to develop Self-Powered Wireless Soft Electronics with Multimodal Energy Harvesting

In this project we will address challenges with the limited battery life of wearable healthcare technologies for continuous physiological monitoring. We will develop self-powered wireless soft electronics that adhere to the skin and monitor physiological vitals.  These electronic stickers will be powered through a combination of on-board batteries and energy harvesting transducers. This project is in collaboration with Carnegie Mellon University, Prof. Carmel Majidi Soft Machines Lab, and Dr. Christopher Tabor at Air Force Research Lab (AFRL).

Energy harvesting will be achieved using thermoelectric and triboelectric power generation from body heat and motion, respectively. LMEE will be integrated into both generators – as

a thermal interface material for thermoelectric heat management and a dielectric elastomer and conductive electrode for triboelectric harvesting.  As part of this NBMC-sponsored effort, Arieca will also explore the use of LMEEs as electrically-conductive elastomers for stretchable circuit wiring and bioelectrodes.

NSF SBIR News Press Release

Arieca Receives an NSF Small Business Innovation & Research (SBIR) Grant to Develop Liquid Metal-Based Thermal Interface Materials (TIMs) Based on the Liquid Metal Embedded Elastomer (LMEE) Architecture

Thermal management issues in the semiconductor industry are driven by a sharp increase in power densities. To resolve these issues, many attempts are being investigated in device packaging to extract the heat generated away and maintain the functionality of the device. Existing thermal interface materials (TIMs) play an important role in transferring the heat efficiently but suffer from challenges associated with interfacial contact thermal resistance, optimized distribution of TIM over the die surface, pump-out and delamination.

This SBIR project supports Arieca’s efforts to create a TIM version of LMEEs, which we call TIMbberTM, to overcome these challenges. Specific efforts will focus on refining the formulation and fabrication to meet customer specifications. This includes improvement of the TIMbber material composition, development of a scalable manufacturing process, and characterization of materials properties for TIM applications.

NASA SBIR News Press Release

Arieca Receives a NASA Small Business Innovation & Research (SBIR) Grant to Develop Space Grade Version of Liquid Metal Embedded Elastomers (LMEEs) for Applications in Aerospace Industry

Elastomers like silicone rubber have a central role in space technologies.  They are used as sealants, encapsulants, connectors — e.g. gaskets, O-rings, etc. — and diaphragms in propellant tanks, docking mechanisms, optical systems, and a wide range of other subsystems used in spacecraft.  Because of their ability to dissipate mechanical energy, elastomers can also be used for vibration mounts and shock absorbers. However, the poor thermal conductivity of existing elastomers can result in damaging hot spots from heat trapping or extreme internal stresses from mismatches in temperature and thermal expansion.  This can be especially problematic for applications in which elastomers are used to seal or encapsulate propulsion systems, electronic instrumentation, laser optics, and other heat-producing components and subsystems.

In this SBIR project, Arieca will work with NASA to explore ways to use LMEEs to address these critical challenges in space technologies.  Specifically, the team will develops a “space grade” version of LMEEs that exhibits the following properties: (i)  negligible outgassing, (ii) withstand wide operational temperature range, (iii) Ability to survive cryogenic exposure and deep freeze storage, and (iv) resistance to embrittlement from irradiation.  Such materials would eliminate the need for additional heat management systems that would otherwise be required to ensure uniform temperature distribution and to prevent heat from getting trapped.
