PulseKit

// Overview

Low-cost vital sign monitoring hardware designed for underserved clinics. Open design, global impact.

In many parts of the world, basic patient monitoring equipment is out of reach — too expensive to buy, too complex to repair, and too proprietary to adapt. PulseKit was designed to change that from the ground up.

Built around widely available components, the device measures heart rate, SpO‍₂, respiratory rate, and skin temperature — logging readings locally and optionally syncing to a simple cloud dashboard over 2G or WiFi. The entire BOM costs under $40 at volume.

Hardware schematics, firmware, and clinic management software are all published under open licenses. We partner with local makers and NGOs to support deployment, training, and long-term maintenance.

WHAT PULSEKIT DOES.

Multi-Vital Sensing

SpO‍₂, heart rate, respiratory rate, and temperature — all from a single wrist-worn device with medical-grade sensor accuracy validated against ISO 80601-2-61.

Offline-First Design

All readings are stored locally on a 32GB SD card. Internet connectivity is optional — clinics in low-connectivity areas lose no functionality whatsoever.

Repairability First

Every component is through-hole or hand-solderable. No BGA, no proprietary connectors. A clinic technician with basic soldering skills can repair any fault.

Alert Thresholds

Configurable alarm thresholds per patient. Audible and visual alerts on-device when readings fall outside safe ranges — no software update required.

// Design Challenges

PROBLEMS WE SOLVED.

Challenge

Medical Accuracy on a Budget

Getting clinically useful SpO‍₂ readings from commodity sensors required custom signal processing firmware and careful analog front-end design. We spent four months on this alone.

Challenge

Power in Off-Grid Environments

Many pilot clinics have unreliable mains power. PulseKit charges over USB-C from any 5V source — solar charger, power bank, or laptop — and manages its own sleep cycles aggressively.

Solution

Local Language UI

The on-device display supports 18 languages with a simple font rendering system. Clinic staff select their language on first boot — no configuration file or app required.

Solution

Supply Chain Resilience

Every critical component has at least two verified alternative part numbers. If one chip is out of stock globally, the BOM can be substituted without changing the PCB layout.
