Worked with leading neuroscientists, designers and engineers to create a world-first novel wearable device and connected mobile app which can actively change how the wearer feels (https://feeldoppel.com). Product sold in excess of 4K units in the USA & Europe delivering particular benefit to users suffering from anxiety, with life-changing effects.It works by creating a silent vibration on the inside of your wrist which feels like the ‘lub-dub’ of a heartbeat. Its natural, psychological effect works in a similar way to music - slower rhythms are calming, and faster rhythms help you feel focused.Selected achievements:•Led technology development from initial ideation and prototyping through to manufacturing and sales, delivering a compliant and scientifically validated connected hardware device to market.•Established research strategies to both engage with users to establish use cases, as well as with research partners to independently validate core technology and investigate underlying mechanism.•Designed custom haptic “heartbeat” from user testing insights and literature, natural gesture-inspire capacitive touch interface. Specified and oversaw delivery of custom transparent haptic actuator for doppel wearable.•Ran product and development teams (10+) across hardware, firmware, mobile (native) and backend to ensure effective cross-functional communication and ingrained customer research and insight sharing throughout product and development teams.•Delivered mobile apps for consumer and research purposes on iOS and Android stores with BLE-connectivity, custom onboarding, resting heart rate measurement, profiles and personalisation features.•Spent over a year in China to establish production and assembly lines across electronics, plastics, casework and assembly, including design for manufacture, sourcing, quality assurance with ODMs and partners.
