Screenless Health Wearables
Present on the body.
Quiet in the day.
Hulin engineers screenless health wearable systems, including wristbands and rings, around comfortable wear, dependable signal capture and a connected experience without an on-device display.
Start a ProjectDesigned around wearing
The connection
is physical.
A wristband meets the body through its strap and enclosure; a ring through its size and inner surface. Fit, movement and the sensor’s relationship to the skin are considered together.
Wristband or ring.
Fit comes first.
The form changes how contact is maintained. Strap adjustment, ring sizing and enclosure geometry influence how the device moves with the wearer.
Mechanical integration, sensor placement and wearing conditions need to be evaluated as one system.
At the skin / In the background
What the wearer sees.
What the system needs.
Optics, contact
and movement.
PPG development can include optical openings, sensor placement, light paths and ambient-light considerations. ECG contact arrangements, skin-temperature sensing and an IMU may be evaluated according to the product brief. The illustrated devices do not establish a particular sensor configuration.
The engineering of continuity
A smaller interruption.
A more complete record.
Continuous-sensing products must account for changing contact, available power and time away from the phone. Continuity is designed across these conditions.
- 01Contact
- Evaluate fit and sensing conditions during rest and movement.
- 02Sampling
- Coordinate sensor activity with the information the product needs.
- 03Storage
- Buffer observations and preserve timing when a phone is unavailable.
- 04Synchronization
- Move available data through BLE while accounting for interruptions.
Power is a shared budget.
Low-power architecture is a system decision. Sensor activity, processing, memory writes, radio scheduling and sleep / wake behavior must work within the battery and wearing requirements. Sampling strategies and data-quality checks are evaluated together; battery life is established through product-specific testing.
The experience continues beyond the device
Quiet hardware.
Context when it matters.
With no primary screen on the device, the mobile application becomes an important part of the product. Binding, device status, synchronization and settings need to be understandable. Health algorithms and software can organize supported observations into daily and longer-term trends, while firmware updates and data continuity are planned across the system.
