Services

At Vagus, we aim at providing comprehensive R&D services that can start at the brainstorming stage based on your ideas or needs, as well as computational modeling, simulation, and experimental validation. See below for specific areas that our team can serve you in.

Sensor and Actuator Services

Soft Sensor & Actuator Development

Soft Sensors

Single or multifunctional devices based on Polymer nanocomposites, smart polymeric materials, or copolymers, etc. Applications: smell sensors, airborne particle sensors, electronic skin, smart textiles, wearables, etc.

Soft Actuators

Soft materials that mimic natural systems or organisms using polymeric materials. Applications: soft grippers, soft robotics, animatronics, etc.

Software & Hardware design for sensors and systems

Machine Learning Algorithms

We are developing various machine learning algorithms based on GNN, MPNN, temporal CNN, Vision Transformers, etc.

Hardware Architecture Design and Integration

With new approaches to computing involving ML and
reprogrammable hardware systems, the implementations of hardware and software are becoming more flexible. 

Systems Integration

We are integrating our solutions into the development of unique sensor systems such as advanced ultrasonic and computer vision.

Ongoing Projects

Video: Using DFT to model degradation of forever chemicals

This video shows how a polarized UV pulse can be used in the effective defluorination of a certain PFAS (PFOA)

Multi-energy Domain modeling & curriculum dev. Services

Multi-Energy Domain Engineering System Modeling

Multi-energy domain systems

modeling, simulation, and analysis of mechatronics systems using the bond graph approach. Our approach allows for modeling and simulation of chemical and some biological systems such as those related to the ATP cycle, MAPK cascades processes, etc. from a pure energy generation, use, and storage perspective.

Curriculum Development

Interactive, cloud-based simulation books for high student engagement. Project-based curriciulum development for mechatronic and smart system courses and labs. For example: Lab-in-a-book textbooks, smart manufactuing, or mechatronic courses and labs.
