About

Alexander A. Altmann is an emerging researcher specializing in additive manufacturing, smart sensing technologies, and wearable systems for human motion analysis and rehabilitation engineering. His work sits at the intersection of 3D printing innovation and functional sensor development, with a particular focus on making advanced sensing solutions more accessible and cost-effective. Altmann's most impactful contribution to date is his 2024 work on a 3D-printed piezoelectric PLA-based insole for gait event detection, which has garnered 26 citations and demonstrates significant promise for controlling lower-limb wearable robotics in assistive and rehabilitation contexts. Complementing this, his research on versatile force sensors integrated directly into 3D-printed parts addresses a critical barrier in robotics and industrial applications — reducing the complexity and cost of sensor integration through fused filament fabrication techniques. His broader portfolio explores piezoresistive force sensors with low creep characteristics for robotic end-effectors, ferroelectret-based wearable sensors for force myography, and novel piezoelectret metamaterials with tunable piezoelectric properties. Collectively accumulating nearly 50 citations across publications from 2023–2024 alone, Altmann's research trajectory suggests a rapidly growing influence in the fields of smart materials, human-machine interaction, and assistive technology development.
