This article focuses on the fabrication and characterization of stretchable interconnects for wearable electronics applications. Interconnects were screen-printed with a stretchable silver-polymer composite ink on 50-μm thick thermoplastic polyurethane. The initial sheet resistances of the manufactured interconnects were an average of 36.2 mΩ/◽, and half the manufactured samples withstood single strains of up to 74%. The strain proportionality of resistance is discussed, and a regression model is introduced. Cycling strain increased resistance. However, the resistances here were almost fully reversible, and this recovery was time-dependent. Normalized resistances to 10%, 15%, and 20% cyclic strains stabilized at 1.3, 1.4, and 1.7. We also tested the validity of our model for radio-frequency applications through characterization of a stretchable radio-frequency identification tag.

“…it follows that after substituting (2) into (1) and removing the components out of the band, rejected by the internal IC-LPF, the minimum amplitude of the output in-band signal at the output of the receiver y mxout (when phases θ SJ = θ I = 0), will be depending upon the amplitude signals of the selfjammer (A SJ ) and the amplitude of received signal (A RX ), assuming A SJ A I ;…”

“…ear field communications (NFC) are being used for identification or payment transactions, in ePassport or travel cards, and also in applications such as embedded sensors [1]. In these latter applications, NFC tags can be totally passive, such as the implantable glucose sensors in [2], but other NFC tags require small batteries, such as those described in [3], where NFC enabled devices collect patient data.…”

In this work, it is investigated the possibility of using near field communication (NFC), normally applied for communicating two proximity devices, to power-up external circuitry, such as low power wireless sensors, or energy scavenging devices. For this purpose, the possibility of combining both features in a single system, able to communicate with neighboring devices via NFC and to transfer power from one device to another (wireless power transfer WPT), has been studied. After taking considerations on antenna design, both for NFC and WPT, a reconfigurable circuitry optimized for data and energy transfer is proposed. The circuit provides optimal close proximity wireless magnetic communications, and is able to use the same device for optimal energy transfer. This feature has been implemented and demonstrated using PCB antennas, NFC reader with a mobile phone or NFC-tag and a circuitry for charging an external Io-Li battery. The results show an improvement of the energy transfer when such circuit capability is turned on. Index Terms-Coupling, wireless power transfer (WPT), nearfield communications (NFC), switching.
