Wiliot, the semiconductor pioneer and innovator, raises a $30m series B for a total of $50m in funding. This follows its demonstration of the first-ever sticker-sized Bluetooth sensor tag incorporating an ARM processor powered solely by scavenging energy from ambient radio frequencies. On the heels of their first successful tests, Wiliot, whose R&D department is based in Israel, closed a Series B round of funding with Amazon Web Services Investment Arm, Samsung Venture Investment Corp. and Avery Dennison. These organizations have joined Norwest Venture Partners, 83North, Grove Venture Partners, Qualcomm Ventures, and M Ventures to raise an additional $30m of funding. “Wiliot’s strategy for battery-free Bluetooth transponders, which sense and communicate without needing specific action by consumers, is very relevant to Avery Dennison’s intelligent label strategy,” explained Francisco Melo, VP & GM, Global RFID, Avery Dennison.
