Industries · Fitness and tracking
Fitness bands, sport trackers, GPS trackers and safety pendants live on the body, in the rain and far from a charger. We take them from idea to factory: industrial design, miniature electronics and firmware, GPS and cellular that keep working, certification for body-worn radios, and manufacturing with our partner factories in China and Pakistan.
The short answer
Wearable device development turns an idea for something worn or carried into a product people trust all day. It covers a small, comfortable design that survives sweat and water, electronics and firmware that last days or weeks on a tiny battery, GPS and radios that keep a fix, the radio-exposure and battery certification body-worn devices need, and manufacturing at a price buyers will pay.
Where wearables go wrong
Fast GPS updates drain a small battery in days.
We budget power per mode before the PCB is drawn.
Smart GPS Tracker, under NDAGPS drops out indoors and between tall buildings.
We plan antenna, GNSS and fallback for weak sky.
GPS sport tracker, under NDASweat and rain corrode contacts and beat seals.
We seal to a target IP rating and protect contacts.
Sealed housing designBulky modules feel heavy on a wrist or lanyard.
We miniaturise the board around the battery.

Certification
FCC RF exposure (SAR)
What it covers
RF exposure limits for body-worn transmitters.
What we do
We place antennas and set power for SAR margin.
EN 50663 and EN 62479
What it covers
EU RF exposure check for low-power wearables.
What we do
We check the 20 mW exclusion before booking SAR.
PTCRB and GCF approval
What it covers
Cellular device approval that carriers ask for.
What we do
We use pre-certified modules to cut retesting.
LTE-M and NB-IoT
What it covers
Low-power cellular that outlives 2G and 3G.
What we do
We set power-saving timers to the update rate.
IP67 and IP68 (IEC 60529)
What it covers
Dust and fresh-water ingress into the housing.
What we do
We add sweat checks beyond the standard IP test.
EN 1811 nickel release
What it covers
Nickel release from metal that touches skin.
What we do
We pick low-nickel metals for skin-contact parts.
FDA general wellness line
What it covers
Where wellness claims end and medical ones begin.
What we do
We keep heart-rate and fall wording to wellness.
Accredited labs test and certify. We design to pass and pre-test, so the paid test is a formality, not a gamble.

FAQ
It depends on the radios, sensors, sealing and app. We start with a feasibility study at $1,000 to $2,000, then give you a fixed price for each stage.
Usually FCC Part 15 and an RF exposure assessment in the US, and CE under the Radio Equipment Directive in the EU. Cellular adds PTCRB or GCF and carrier approval, and the battery needs UN 38.3. Low-power Bluetooth-only devices can often skip SAR testing.
Phones manage about 4.9 m under open sky, and accuracy drops near buildings and trees. Indoors, GPS often fails completely, so good trackers add Wi-Fi, cell or Bluetooth-beacon fallback and assisted GPS for faster fixes.
Avoid 2G and 3G-only designs, because those networks are being switched off. LTE-M suits moving trackers and wearables, and NB-IoT suits static assets. Both save power, but the network sets the final timers.
Often yes, as long as it stays a general wellness product with no claims to diagnose or monitor a disease. Claims like that make it a medical device. Fall alerts should alert a carer, not promise to prevent falls.
Set the target IP rating early and design seals around it. IP tests use fresh water only, so sweat needs its own checks. Protect charge contacts or use wireless charging, and choose low-nickel metals for parts that touch skin.
