Project HiJack

ProjectHiJack is being developed by researchers at the Electrical Engineering and Computer Science Division at the University of Michigan, a DIL collaborator. HiJack is a hardware/software platform for creating cubic-inch sensor peripherals for the mobile phone.

HiJack devices harvest power and use bandwidth from the mobile phone’s headset interface. Several energy harvesting power supply designs are possible—with tradeoffs in efficiency, cost, and complexity—but the HiJack platform fundamentally strives to enable a new class of small and cheap phone-centric sensor peripherals that support plug-and-play operation.

HiJack has been tested with the iPhone 3G/3GS/4G, iPod Touch, and iPad devices, and work is underway to support Android and Windows Phone 7 devices as well. The HiJack platform has served as the basis for a number of low-power sensor and signal conditioning applications, including EKG monitoring for health interventions, gas concentration (CO, NOx, O3, and SO2) monitoring for environmental health assessments, and soil moisture analysis for agricultural interventions.
