Microelectromechanical Systems geared towards biological applications (BioMEMS). Microactuators,
microvalves, microflowmeters, microchannels, and other structures are used to form microfluidic systems,
energy harvesting devices, physiological monitoring/sensing systems, etc.

Integrated Circuits |
|
|
| |
Our focus is on analog integrated circuits (especially low-power circuits for implantable
systems). Design and simulation is performed at Northeastern, and chips are fabricated by MOSIS.
We have worked on Analog-to-Digital Converters, Voltage-Controlled Oscillators, Low-Noise Amplifiers,
Voltage References, and more.

Nanotechnology |
|
|
| |
Our work in this area resembles the term 'nanotechnology' in that it is broad.
Work in the area includes carbon nanotubes, magnetic nanoparticles, and nanofluidics to name a few. |

Implantable Micro- and Nano-Systems |
Our research pulls together sensors, actuators, and circuits aimed at creating
stand-alone systems for use in vitro and in vivo.
Current projects include: energy harvesting technology compatible with highly sensitive regions of the body,
ultra-miniature pressure sensors for intraocullar pressure monitoring (also usable elsewhere), and ultra low-power
microactuators. |

High-Throughput Screening |
|
The core of this system combines MEMS microfluidic sample-handling components
with functionalized magnetic nanoparticles. The targeted applications include early cancer detection,
prenatal diagnosis, and more. |

This topic is approached from three directions: prevention, understanding,
and restoration.
Prevention: We are investigating various methods of decreasing the volume required for cell phones,
portable audio devices, etc. via the incorporation of noise-canceling technology.
Understanding: Our high-density microelectrode arrays are used to interface with neurological systems
to gain insight into their behavior. Microfluidics can be added to allow for a clearer understanding of the effects of
various drugs on the systems. We are seeking additional collaborators interested in using this technology.
Restoration: We are interested in using low-power circuits and microelectrode arrays to restore
hearing in the profoundly deaf, and also use low-power circuits to improve the performance of hearing aids. |

We create robust inertial sensors for acceleration and vibration detection. |
