  • Patent number: 11048990
    Abstract: One example is directed to a reader device having a first resonance circuit and being configured to interrogate one or more other remotely-located resonance circuits, each associated with a second resonance circuit which may be part of a passive sensor circuit. The first resonance circuit is operated to cause the inductively-coupled oscillating signal to be swept over a range of frequencies and therein cause a jump or sudden transition in a frequency of the oscillating signal while the first and second resonance circuits are in sufficient proximity for inductively-coupling via an oscillating signal via their respective resonance circuits. Sensing circuitry may be used to detect the jump or sudden transition in the frequency of the oscillating signal and, by way of or in response to an indication of timing and/or a set of inductively-related parameters, data is conveyed from the sensor to the reader device via the inductively-coupled oscillating signal.

  • Publication number: 20200401042
    Abstract: One or more embodiments relate to an electrically conductive polymer with a crosslinkable additive. The electrically conductive polymer is a directly photopatternable Poly(3,4-ethylenedioxythiophene):poly(styrenesulfonate) PEDOT:PSS film with cross-linked network made of a plurality of monomers. The directly photopatternable PEDOT:PSS film PEDOT as such has a better conductivity and stretchability compared to its other counterparts. The directly photopatternable PEDOT:PSS film can further be supplemented with poly(ethylene glycol) diacrylate (PEGDA) which can help with the removal of PSS. Advantageously, the PEGDA supplemented PEDOT:PSS film can exhibit a larger charge storage capacity.
