Self-Powered Piezoelectric Nanotattoos
Self-powered Nanotattoos capable of passive wireless communication have been created by researchers in Istanbul.
(Spectrum)
The backscattering-based nanotattoo sensor (BNTS) tattoos were developed by Kristen D. Belcastro, a lecturer at Yeditepe University, in Istanbul, and Onur Ergen, the vice chair of research and development at the Istanbul Technical University’s department of electronics and communication. The tattoos are composed of two inks—a zinc oxide ink containing embedded nanowires atop a graphene aerogel conductive ink. The two inks are painted onto the skin simultaneously via separate needles. Ergen says there is also some aerogel in the ink containing the nanowires, though at a lower ratio than that in the lower layer, and as a result, the two inks bond on contact.The devices’ wireless communications rely on the creation of electrical signals from piezoelectric activity, made possible as the tattoos change shape, which converts mechanical energy into electrical energy. The tattoos’ wireless networking infrastructure uses a smartphone to bounce signals off the tattoo and receive data, with a broadband modem as a helper device.
“When the painted tag receives the radio frequency (RF) signals, it reflects some of the signals to establish an up-link with the smart phone reader while the smart phone establishes a down-link with the tag,” the researchers wrote in their paper. “From these communication links, the smart phone can continuously monitor the BNTS and process the information using artificial intelligence algorithms.”
Ergen says that this communications approach, called ambient backscattering, is similar to RFID but does not rely on a limited number of allowed frequencies.
