This paper presents an energy harvesting device for body centric sensor systems. The focus of collecting energy is put in the sensor far-field and in a large frequency bandwidth. The proposed device comprises of the logarithmic spiral textile antenna paired with a simple rectifier circuit. The antenna is designed and manufactured by embroidered conductive yarn into denim material. The antenna prototype has been tested. Several rectifier circuit topologies were simulated and the DC voltage at the rectifier output is obtained by simulation.
