Correct, to continuously power the RFID over a long period, integrating solar cell or a triboelectric nanogenerator with the supercapacitor is a good option, and we are doing lots of research to optimize and stabilize the performance.

Dear Qiu,

Many thanks for your very prompt – and clear – reply

India’s Rs 2,000 currency note is 110 micron thick

And 1 cm sq area for embedding microsupercapacitor , should not pose any problem

Extremely thin RFID sensors are also available – and getting as cheap as few cents a piece

But since the charge from microsupercapacitor can power that RFID for only 1 hour , it may not be of much use if that pile of currency notes is just lying in a cabinet / vault

Although, if that currency note is lying in a wallet / purse and handled , now and then ( in order to make “ cash payments “ ) , then I suppose it will build up the charge in microsupercapacitor and power the RFID

Am I correct ?

Dear Hemen:

The typical power consumption of RFID is ~10 µW, and Energy density of a microcapacitor can easily go 1 mWh/cm3, which means a microsupercapacitor with 1 cm3 volumn can power the RFID for 100 h. As you said, you want some thin devices, take 100 µm thickness for example, a microsupercapacitor with 1cm2 area and 100 µm thickness can power the RFID for 1h.

Also, you don't need to continuously power the RFID, thus it is practical to do so.

Regards

Qiu

Dear Qiu / Jr-Hau He,

I read about your research on this subject at :

Congratulations on a discovery of ( possibly ) , immense economic consequences

Here is what I have in mind :

Corruption is the biggest economic evil , which continues to fuel “ inequity “ among the rich and the poor

Corruption starts with tax evasion and subsequent use of Black Money generated – most of which , is in the form of high denomination currency notes , piling up in the cabinets and vaults of the tax-evaders

Currently , there is no technology to trace / track such piles of hidden high denomination currency notes , although there has been lots of “ talk “ on embedding such currency notes with RFID sensors , to enable tracking

Some months back , an officer of the Australian Government announced intention to do just that

I have , myself , been urging the Indian Government for over 2 years , to embed RFID in newly printed notes of Rs 500 and Rs 2000

But , I understand , RFID need a source of power , in order to “ announce “ its location

And , so far , it has not been possible to embed a battery within the thin currency notes , which can power RFID

Is it possible that one of these days , your research can supply such power to embedded RFID ?

I would highly appreciate your views on this

With Regards,
