In this paper, we presented \names, a first of its kind system that uses 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 beamforming of WiFi transmissions to enable a wearable receiver to harvest up to 800$\mu$W of energy,
a receiver located 3 to 4 meters away. \name couples this harvesting with 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
smart event triggering to duty cycle a full wearable device that uses 40 or that \name can be a viable approach for batteryless wearable sensing. We also identify open issues to tackle, before \name can
