Ontech CEMFSpatial computing and wearables
Gesture control through the housing
High-definition spatial sensing at very close range, in any light, through the product housing and without biometric data.
Electromagnetic field on a chip
Ontech CEMF®
A controlled electromagnetic field on a chip detects people, objects, materials and movement without line of sight or contact.
How CEMF works
- 01
Generate
The CEMF sensor creates a controlled electromagnetic field around the device, shaping its strength, frequency and direction.
- 02
Disturb
People, objects and movements interacting with the field create measurable, characteristic disturbances.
- 03
Interpret
Patented algorithms identify an object's features, composition and movement, in high definition and in real time.
- 04
Decide locally
Working mainly in the analogue domain, embedded algorithms decide on the device, with no data connection and no personal data.
What makes it different
- No line of sight needed
- Detects through materials
- Non-contact operation
- Ultra-low power
- Analogue, on-device processing
- No personally identifiable information
The Ontech ASIC
The CEMF ASIC generates and controls the field and performs signal analysis, processing, data conversion and data analysis in one chip, built for customisation and mass production.
- Integrated sensing and processing
- Field generation, signal analysis, data conversion and data analysis in one analogue ASIC with ADC, clock, references and LDOs.
- Built for volume
- Standard technology (TSMC), compact form factor, low voltage, minimal external components and low unit cost.
Engineered in Seville
Our core technology and prototype R&D teams work in-house, from field simulation and chip design to algorithms and engineering samples, under ISO 9001, EN 9100 and UNE 166002 certified processes.
