Wireless Charging for IoT devices


Published on

Humavox wireless charging solution designed to solve many of the usability flaws experienced by users of IoT (Internet of Things) devices mainly short battery life and the numerous power cords. Wireless charging sustains the true vision of IoT: cordless mobility, flexible design and zero concern about remaining battery.

Wireless Charging for IoT devices

  1. 1. Wireless Charging Untangling Cordsin theAge ofConnected People ByOmriLachman Co-founder&CEO,HUMAVOX
  2. 2. Ikeeprunning intothis notification
  3. 3. My lifeis stacked with these…
  4. 4.  Mostportableelectronic devices arepowercorddependent  Somestill dependonprimarycells which means replacing batteries  With #IoT visionbecoming areality,users topexisting electronics with wearabletech  Each device has differentpowerrequirement andoperatingtime  Mostdevices featureuniqueUSB based powerinterfaceports  Resulting in more cables in our life #IoT is facinga usabilitychallenge
  5. 5. Frustrated User is a Red Flag FromAnnoying toShow Stopper Toomany different USB interfaces Toomany cordsper userin alllife environments Insufficientpower portsin our environment User‘enslaved’and discouraged bybad &inconsistent functionality Devices are becoming toosmall forUSB port Inabilityto trackpower betweendevices
  6. 6. • How will we treat ourdevices when not in use (Bed time, traveling, bathing, Etc.) • How will you charge them? 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
  7. 7. Retire the Wire
  8. 8. Wireless Charging Definition(Wiki): “Inductivecharging(alsoknownas"wirelesscharging")usesanelectromagneticfieldto transferenergybetweentwoobjects.Thisisusuallydonewithachargingstation.Energyissent throughaninductivecouplingtoanelectricaldevice,whichcanthenusethatenergytocharge batteriesorrunthedevice” Nikola Teslafirstdemonstratedwirelesselectricitytransfer in1891(TeslaEffect) Developmenteffortsgainedspeedaround2007by a varietyof entitiesthatformed standardsbasedonthe above
  9. 9.  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

  12. 12. It should be for everyone
  13. 13. Size limitation disables global standardization

  22. 22.  Wireless Chargingis the “gatekeeper” of #IoT devices functionality  It unifies chargingfor multiple devices  It reduces the numberof cords inour lifesubstantially  Itunleashes HWdesign existing constrains (USBPort)  It serves as a guiding cloud layerthat helps the industry &users to improve usability  Improvepower consumption andsupply efficiencywhich prevents waste of energy Summary Finally, it also sustains the truevision of #IoT…..
