Abstract
Integration of Wireless IoT Wearables on a flexible substrate has been hindered by the unavailability of flexible RF frontends for fabric or Polyimide-based circuits. In addition, existing reference antennae are not designed for operation in human proximity. Moreover, the size and lifetime of batteries hinder the realization of a Fit-and-Forget solution.Presented, a flexible Bluetooth Low Energy (BLE) node, with a bespoke detuning-resilient antenna for Body Area Networks (BAN). Furthermore, the system can be powered entirely from a flexible Ferro-electret energy harvesting insole, producing sufficient energy for an intermittent BLE beacon, advertising every 10 steps. The insole can be utilized to prolong battery life for high duty-cycle applications by >80%. The designed flexible circuit can be seamlessly adjusted adding multiple 2.4GHz wireless protocols support, based on Texas Instruments’ CC26XX 2.4 GHz wireless SoCs.
