Pixel and impedance measurement circuit characterization and analysis for active Electro Wetting on Dielectric (EWOD) arrays in thin film technology

Lab On a Chip (LOC) is the future for key biological applications such as high throughput PCR and faster drug discovery processes. Electro Wetting on Dielectric (EWOD) is an alternative to other more expensive microfluidic approaches due to its potential to manipulate numerous droplets using active matrix (AM) addressing. 

A first step towards active EWOD (aEWOD) arrays is to adapt the active matrix addressing techniques into the EWOD specification space. The main one is the 2T1C circuit which will be characterized during the internship.

A look into the future of aEWOD shows the need for impedance measurement circuits to identify the presence (or absence) of droplets and possibly their composition. The more experimental part of the internship will focus on measurements, and characterization of such a circuit with the possibility of a more in-depth study and simulations if time allows it.

Your main roles will be:

• Aid in the measurement and characterization of a high voltage aEWOD oriented 2T1C circuit.
• Perform the circuit analysis of the measurement data of the 2T1C circuit along with statistical significance metrics.
• Measurement and analysis of an experimental impedance measurement circuit for aEWOD applications.
• System study/simulations on how to improve impedance measurement.

What you can expect:

• Acquire knowledge and training regarding measurement setups for ICs.
• Acquire knowledge and understanding of the statistically significant specifications of a circuit.
• Direct contact with both experimental technology and circuits

Who you are:

• (Required) MSc. In Electrical Engineering or similar
• (Preferred) Some experience measuring electrical circuits/ICs
• (Preferred) Familiarity with IC circuit design and analysis
