The document discusses the challenges and limitations of traditional power sources for portable electronic devices in the context of the Internet of Things (IoT), highlighting issues such as excessive cords and varying USB interfaces. It emphasizes the potential of wireless charging, defined as inductive charging, to improve usability and efficiency, reduce dependency on wires, and enhance device design. Ultimately, it posits that wireless charging serves as a crucial element for optimizing user experience and sustainability in the IoT ecosystem.

Can you keep track ofbattery life with multiple devices? • Where andhow will you store your,sensors? • Existing charging methods can’t fit in this space • How can we change that? In theAge of #IoT, Power is Not Justfor Charging. Power InterfacingDictates NewUsability Patterns

Requirescoupling conditions by device placement i.e dependency on user Optimum conditions are almost neverarchived Lower efficiency, waste heat -Themain disadvantages of inductivecharging are its lower efficiencyand increased resistive heating in comparison to direct contact Slower chargingdueto the lower efficiency Inconvenience– with the device placed on a chargingsurface, theuser can’t interact with it Main Disadvantage:Usability thatLeads to a Chainof flaws
