\label{sec:conclusion}
In this paper, we presented \names, a first of its kind system that uses
beamforming to harvest up to 800$\mu$W of energy using WiFi transmissions on
a receiver located 3 to 4 meters away. \name couples this harvesting with
smart event triggering to duty cycle a full wearable device that uses 40 or
more mW of power. We demonstrated this via detailed systems and user study
results with a prototype wearable sensing device that periodically transmits
sensor data.% \raj{what do we say here?}
beamforming of WiFi transmissions to enable a wearable receiver to harvest up to 800$\mu$W of energy,
while located 3-4 meters away. \name couples this harvesting with smart event triggering, using a kinetic motion sensor, to duty cycle a full wearable device whose instantaneous power drain is 40 mW or higher. Via measurements and user studies performed in a representative office setting, we see
that \name can be a viable approach for batteryless wearable sensing. We also identify open issues to tackle, before \name can
be ubiquitously deployed in a production environment.
