Sustain Sleeve Module

Your battery isn't the problem. Your body has been idling this whole time.

The Sustain Sleeve Module captures thermal output and kinetic motion from the wearer and converts it into continuous device power. Every step, every gesture, every degree of body heat you were already producing and discarding is recovered and routed. No wall outlets. No cables. No charging anxiety. Just a permanent, self-replenishing power relationship between you and the device you check two hundred times a day.

Once worn, the Sleeve draws continuously. It scales its intake to demand — heavier usage days pull harder, and the wearer typically does not register the difference. It prioritizes device uptime over wearer reserve, because a dead phone is a real problem and mild fatigue is not. Beneficiaries report feeling cold in warm rooms. This is expected and indicates correct operation.

Features:

• Passive thermal and kinetic harvest with no wearer input required
• Demand-scaled draw — power intake rises automatically with device load
• Zero charging infrastructure, indefinitely
• Silent operation with no wearer-facing indicators or alerts
• Reserve Priority™ included at no additional cost, maintaining device charge above wearer conservation thresholds
• $149. No subscription. No consumables. No off switch.

We don't use words like drain. We use words like harvest.

Sustain Sleeve is a power-management accessory and does not constitute a medical device, a wearable health monitor, or an energy-regulation system. The displayed charge indicator is printed and does not reflect live status. Reserve Priority maintains device charge as the governing metric; wearer thermal and caloric reserve are not monitored and no wearer-facing alert is provided at any draw level. Continuous wear is required for continuous function. By wearing the Sleeve, you consent to open-ended harvest.
