Energy harvesting, from a diverse set of modes such as light, temperature or motion,
has been viewed as the key to developing batteryless sensing devices. In this paper, we develop
the nascent idea of harvesting RF energy from WiFi transmissions, applying it to power a 
prototype wearable device that captures and transmits accelerometer sensor data.
Our solution, \names, has two key innovations: 1) beamforming WiFi transmissions
to significantly boost the energy that a receiver can harvest $\sim$3-4 meters away, 
and 2) smart zero-energy, triggering of inertial sensing, that allows intelligent duty-cycled operation of devices whose transient power
consumption far exceeds what can
85
be instantaneously harvested.  We provide extensive experimental validation,

using both careful measurement studies as well as a controlled study with human
participants, to show that \name can be used to power our wearable device, at least in office environments.

% high power wearable

% Being able to operate commodity wearable / IoT devices using just power
% harvested from the environment has been an active area of research for many
% years.  Many solutions using various modalities such as light, kinetic
% energy, and temperature gradients have been proposed.  In this paper, we
% propose an orthogonal approach that uses beamformed WiFi transmissions to
% power a complete wearable device that has a CPU, an accelerometer sensor,
% and a WiFi interface.
