Creating smart medical devices of tomorrow

Using micro and nanoscale transducers, LIMR is aiming to create  next generation of implantable medical devices with smart functionalities and superior chronic reliability.



Beyond the classic examples of hospital beds and lift systems, actuators of miniature scale have a greater range of medical utility including surgical instrumentation, drug delivery, and neurostimulation. At LIMR, we are developing a wide range of magnetically (wirelessly) powered microscale actuators for various neurological, oncological, ophthalmological, and addiction-related therapy.


An early diagnosis is key in the successful treatment of many serious illnesses. For example, the imbalance of neurotransmitters in the brain has been linked to many neurodegenerative and psychiatric disorders. To better understand the role of brain chemistry in various neural trauma and other environmental stimulants, we are developing a number of implantable electrochemical sensors.

Anti-biofouling strategies

The reliability of chronically implanted medical devices is often poor, especially for implanted sensors. The body’s immune system often fights against the implants with various biofouling materials. By combining a number of our technology, we are developing a number of novel passive and active anti-biofouling strategies including biomimetic nanotexturing, zwitterionic conductive polymer, and others to prolong the lifetime of implantable smart devices.

Neural interface

Electrical stimulation of the nervous system is now widely used to treat various neurological issues such as chronic pain, hearing, and visual impairments, dystonia, epilepsy, etc. In collaboration with colleagues from the industry and academia, we are investigating ways to improve the functionality and the reliability of microscale neural interface devices using novel designs and materials.
