Novel Surface Restructuring Technology

As the number of people with health conditions requiring implantable, long-term medical devices grows, so too comes the need for enhanced device functionality, specificity and effectiveness.

Novel surface restructuring technology, such as the miniaturisation of electrodes and microelectrode arrays, is just one way innovators are working to boost the performance of these devices.

One example is the Hierarchical Surface Restructuring (HSR) technology from US-based Pulse, which works to improve the electrochemical performance of electrodes and microelectrode arrays by enhancing their surface topology and characteristics.

“…HSR technology optimizes the electrodes’ surface topology by bombarding the surface of the electrode with ultra-fast, ultra-short and high-energy laser pulses, [which then] produce topographic features comprised of varying length scales,” said Pulse in a blog.

“This surface restructuring technique increases the electrode’s available electrochemical surface area that in turn gives rise to charge storage capacity, and specific capacitance while reducing impedance.”

Benefits of such technology, Pulse states, include surface tunability; suitability for a range of sensing, recording and stimulating uses; ultra-high surface area; “unprecedented” charge storage capacity enhancement; and scalability on commercial market.
