design-acoustic-levitation SKILL.md skillA
design-acoustic-levitation from pjt222/agent-almanac is an agent skill: a SKILL.md folder an AI agent loads when a task calls for it.
mdr add pjt222/agent-almanac/design-acoustic-levitation@v1.0Pins v1.0 in mdr.lock. Pin the fingerprint instead.

Design an acoustic levitation system that uses standing waves to trap and suspend small objects at pressure nodes. Covers ultrasonic transducer selection, standing wave formation between a transducer and reflector, node spacing and trapping position calculation, acoustic radiation pressure analysis, and phased array configurations for multi-axis manipulation. Use when designing contactless sample handling for chemistry, biology, materials science, or demonstration purposes.
Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.
What the file says
# Design Acoustic Levitation Design and validate an acoustic levitation system by determining the acoustic radiation pressure required to balance gravity, selecting transducer and reflector geometry to form a stable standing wave, computing the positions and trapping strength of pressure nodes, and verifying that the trapped object is stable against lateral and axial perturbations. ## When to Use - Designing a contactless sample holder for chemical or biological experiments - Building an acoustic levitation demonstrator for education or outreach - Evaluating whether a given object can be levitated acoustically (size, density, and frequency constraints) - Selecting between single-axis (transducer-reflector) and phased array configurations - Calculating the node positions and trapping forces for a given transducer frequency and geometry - Extending a single-axis levitator to multi-axis manipulation using phased arrays ## Inputs - **Required**: Object properties (mass, density, radius or characteristic dimension, compressibility if known) - **Required**: Target levitation medium (air, water, inert gas) with its density and speed of sound …

How to install
mdr add pjt222/agent-almanac/design-acoustic-levitation@sha256:5667299fdf46a1dfThe line at the top of this page pins the label v1.0, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
