Silicone Elastomer (EcoFlex) Strain Sensors + Mechanically Isolated Stretchable Sensors

The properties of elastomer-based components change when pressure or strain is applied. Mechanically decoupling the strain of the component area from the strain of the elastomer substrate would enable stretchable components that are stable with applied strain.

Metal Oxide Sensor Stability in Airflow

Sensor response with P-I control

Top view of metal oxide sensor

In this project, we investigate the stability of metal oxide gas chemical sensors in windy environments. Controlling the resistance of the on-chip heater resistor using P-I control reduces cross-response to airflow.
