BPNX1029: Multi-Mode Multi-Direction High-Resolution Tactile Haptics and Sensing Duo-Functional Device using Piezoelectric Metamaterial

2025

Texture sensing and feedback are critical milestones for unlocking truly dexterous robotics, advancing human-machine interaction, and enhancing teleoperation tasks. While existing systems utilizes pneumatics, vibration motors and other elementary methods to provide basic feedback, they lack the capability to translate data into rich, high-resolution haptic displays required to replicate the nuanced spectrum of human touch. Here, we aim to develop the first-ever fabrics capable of both high-fidelity contact sensing and reproducing touch experiences with the resolution and complexity of...

The development of 3D MEMS devices has enabled innovative sensor designs with enhanced functionality, yet conventional fabrication methods often impose geometric and process limitations. This work presents a micro-3D-printed tactile sensor, integrating 3D piezoelectric, capacitive, conductive and dielectric elements with a compliant mechanism to achieve high sensitivity and force decoupling capability. The sensor is fabricated using a multi-material digital light processing (DLP) method, followed by selective metallization to define conductive regions, enabling seamless...

BPNX1013: 3D Printing of Architected Hydrophones with Designed Beam Patterns

Victor Couedel

2025

Piezoelectric hydrophones are crucial for underwater applications such as communication and seafloor mapping. Limited by the brittleness of piezoelectric ceramics, conventional manufacturing methods restrict hydrophones’ shapes to simple geometries such as disks, cylinders, or spheres, which limits the sensitivity, directivity pattern, and working frequency bandwidth of the device.


We are developping a new class of high-performance 3D printed piezoelectric hydrophones consisting of rationally designed micro-architectures. Using a high-...

BPNX1014: Data-Driven Design of Metamaterials

2025

The rapid development of additive manufacturing technologies has enabled the fabrication of truss metamaterials, i.e., a novel class of lightweight-yet-strong materials with engineered complex hierarchical structures. Manipulating the architecture over chemical composition dramatically expands the achievable materials design space, allowing to largely control the mechanical response of metamaterials. Despite the great advances made in this area, designing three-dimensional (3D) truss metamaterials under complex or extreme conditions with programmable response is still a...

BPNX1033: Multi-Objective Inverse Design of Impact Resistant Metamaterials Under Varying Strain Rates (New Project)

Anish Satpati
Marco Maurizi
2025

This work pertains to the multi-objective inverse design of impact-resistant metamaterials under varying strain rates. Impact-resistant materials are desirable in a wide range of applications, such as sports, automobiles, military, and aircraft, to name a few. Existing literature deals with refining these structures by performing quasi-static finite element (FE) simulations and then verifying them experimentally, which is a time-consuming and expensive process. Moreover, beyond the low-velocity regime, quasi-static simulations are not representative of real-world dynamic...
