Title of Process/ Know-how/ Product/Design/Equipment
Plastic chip electrode (PCE)
Application/Uses/Problem being addressed
Multipurpose electrode platform.
The electrode has been successfully used in electrochemical sensing, electrocatalysis and electrometallurgy by ours as well as other collaborative groups. The electrode is multipurpose in nature and can be used in any electrochemical application in aqueous media in a wide pH window. Although the electrode is not fit for non-aqueous medium.
Electrode in glucometer, sensors, fuel cell etc. after specific application modifications
Salient Technical Features including Competing Features/ Impact
The screen-printed electrode (SPE) are manufactured by printing different types of ink on plastic or ceramic substrates and conveniently used in miniaturized laboratory as well as commercial electrochemical sensing devices. There are several bottlenecks for SPE such as delamination of conducting layer, cannot be used in high current applications, requires high level of expertise, difficulty in scaling up etc.
We have developed a general-purpose electrode the “Plastic Chip Electrode” (PCE). PCE is a bulk conducting, self-standing, composite electrode of carbon (graphite) and polymer (PMMA). The fabrication process in fully spontaneous and hence is highly simple fabrication process as well as highly cost-effective. It can sustain as high current density - 500 mA/cm2.
Demonstrated in: voltammetry’s (CV, ASV, DPV), impedometry, electro catalysis, electrometallurgy current collector in supercapacitor, platform for solid-state reference electrode.
Lightweight, bulk conducting, moderately stable thermally & mechanically,\biodegradable (if prepared using biodegradable polymer).
TRL Level & Scale of Development:
Electrodes are made at several inches scale
Business scope & opportunity (in terms of scale, cost, market etc.):
No similar product available in the global market to the best of our information. PCE is going to be at least 100 times cheaper compare to the existing products having common applications, mostly due to lower material cost, easy fabrication steps and having extremely high shelf-life
