# Psyche_Field : Interactive Energy Harvesting in Instruments
> Philosophical Position (under Pneuma)
Psyche_Field reflects the invisible thread between maker and made,
where the instrument lives by the hand that plays it,
and remembers not just what you play — but how you move, sweat, and breathe through it.
> Core Principle
Psyche_Field treats the player-instrument relationship as an energetic loop, where bodily motion, contact, vibration, and EM presence are harvested and translated into usable energy or feedback signals.
Rather than relying on batteries or digital systems, the instrument feeds itself through the gestures and bioelectric presence of the performer.
> Harvesting Modalities
1. Triboelectric Generators (TEGs)
-
Embedded in surfaces touched by skin (e.g., pickguard, neck contact points, volume knob).
-
Use friction/contact-separation from player’s hand to generate small voltages.
-
Materials: PTFE, silicone, graphene-enhanced films vs. skin, treated wood, or conductive textiles.
Use: Micro-powering low-draw memory circuits, LEDs, slow modulations.
2. Piezoelectric Harvesters
-
Bonded to structural elements (underside of soundboard, neck heel, control cavity walls).
-
Convert vibration and pressure from playing, picking, strumming into voltage.
-
Multiple piezos may be tuned to different mechanical frequencies.
Use: Powering dynamic filters, analog delays, memory traces, or passive displays.
3. Electromagnetic Coils
-
Placed near string paths or motion axes (e.g., near bridge or headstock).
-
Detect relative motion of ferromagnetic strings or even induced EM fields from the player.
-
Can also act as energy inductors or passive modulation sources.
Use: Charge pumps, expression-driven LFOs, proximity-based gating.
> System Architecture
> Functional Output Paths
-
Signal Expression Biasing: Subtle changes in circuit behavior (e.g., gate opening, tone bleeding, fuzz character) based on harvested energy pattern.
-
Self-Modulation: Dynamic circuits shift response based on how much energy is accumulated (like an internal breathing rate).
-
Sensory Feedback: LEDs glow subtly based on energetic intensity, or faint vibrations returned to player (via haptics).
-
Intermittent Memory Triggers: Charge spikes trigger stored micro-patterns or sonic echoes, reflecting past energy buildups.
-
Circuit Awakening: Certain parts of the signal path only activate when enough energy is gathered from interaction (symbolizing “relationship”).
> Design Notes
-
No battery reliance — only stored motion-generated energy or EM presence.
-
Ideal for modular integration: passive expansion into control voltage world, or guitar FX circuits.
-
Minimal digital — if any, low-draw analog-friendly MCUs for adaptive memory, but preferably fully analog neuromorphic.
