In-ear biosensing platform: one component. No added sensors.
AuriSense is the first MEMS-based platform that enables real-time health monitoring, wear detection, and heart-rate sensing — all while playing high-quality audio.
Built on USound’s proprietary ultrasonic algorithm and designed for use with our MEMS speakers, AuriSense delivers precise in-ear biosensing with zero added sensors — transforming everyday TWS earbuds into intelligent health wearables.
Simultaneous Audio + Biosensing
USound MEMS speakers operate at ultrasonic frequencies while delivering wide-range audio, allowing continuous health tracking without compromising sound quality.
No extra hardware
AuriSense enables biosensing through existing audio components — no photodiodes, infrared proximity sensors, or additional receivers.
Biosensing in all environmental conditions
Engineered for dynamic environments, like workouts or commutes, AuriSense maintains reliable performance across movement, noise, and skin-tone variability.
Precise wear detection
AuriSense provides accurate in-ear detection using the same ultrasonic path, replacing traditional IR-based sensors and reducing the bill of materials.

Greip 1.1 + AuriSense: Fast-Track your Biosensing TWS
To accelerate your product development, AuriSense is fully compatible with Greip 1.1 — USound’s dual-speaker audio module featuring:
- MEMS Conamara tweeter for high-frequency detail.
- OBO Pro.2 electrodynamic woofer with Silicon Rubber Technology for enhanced low-end output.
- Tarvos 1.0 MEMS amplifier, matched to the tweeter for clean, efficient drive.
Greip 1.1 is available for direct integration into your TWS designs — no need to redesign from scratch. Pair it with the AuriSense algorithm to unlock advanced health monitoring, wear detection, and heart-rate sensing in your next audio product.
