Transmitter

What Transmitter does

Sendsor GmbH is a privately held German medical sensor technology company founded in 2004 as a spin-off from the Technical University of Munich. The company develops and manufactures silicon-free hot-wire anemometry sensors for medical applications in respiratory medicine, spirometry, ventilation, infusion, and E-Health. Its core technology uses a heated micro-wire to detect heat loss proportional to flow velocity, producing a high-resolution linear flow signal at a 200 Hz sampling rate with sub-1% measurement deviation. The company operates from a cleanroom-equipped facility in Grafing bei München, Bavaria, and emphasizes in-house precision machining, plasma processing, and quality assurance.

The product portfolio comprises three core sensor elements — the F30 bidirectional flow sensor for spirometry and ventilation, a CO2 capnography sensor for anesthesia and intensive care, and a Microflow sensor for microliter-accurate drug delivery and infusion. All three products are fully autoclavable, chemically resistant, and offer up to ten times the operational lifespan of conventional silicon MEMS sensors. Sendsor also markets Lufttacho, a CE-compliant child-friendly spirometer developed in partnership with PARI that integrates the F30 sensor and supports telemedicine and pediatric therapy monitoring.

The business model is B2B sales of sensor components to medical device manufacturers for OEM integration into respiratory, ventilation, spirometry, infusion, and connected health devices. Pricing is not publicly disclosed and is presumed to be quote-based and application-specific. Customers span home care ventilation, ICU ventilation, emergency medicine ventilation, drug delivery, E-Health, sports medicine, lifelogging, and liquid handling. Distribution is direct to OEMs, with a stated global scope. The company is led by Managing Director Dr. Alexander Scholz, and ownership appears founder/management-controlled with no disclosed venture capital or private equity backing.

Core offering

Sendsor GmbH develops and manufactures precision hot-wire flow and analysis sensors (F30, CO2, Microflow) for medical device manufacturers to integrate into respiratory, ventilation, spirometry, infusion, and E-Health products. The company also offers the Lufttacho, a CE-compliant child-friendly spirometer built on its F30 sensor for telemedicine applications.

Product overview

SENDSOR entwickelt und fertigt eine Familie von Hot-Wire-Flow- und Analyse-Sensoren für medizinische Anwendungen. Das Kernportfolio umfasst drei Sensorprodukte — das F30 Sensorelement (bidirektionaler Flow-Sensor für Spirometrie und Beatmung), den CO₂ Sensor (Kapnographie für Anästhesie und Intensivmedizin) und den Microflow Sensor (Mikroliter-genaue Flow-Messung für Infusion und Drug Delivery) — alle auf der nicht-siliziumbasierten Hot-Wire-Anemometrie-Technologie basierend, vollständig sterilisierbar und in Deutschland gefertigt. Ergänzt wird das Portfolio durch das End-User-Produkt Lufttacho, ein elektronisches Spirometer für Kinder, das den F30 Sensor in einer CE-konformen, App-basierten Lösung für Telemedizin einsetzt.

Others

• Getinge: Global manufacturer of ICU and surgical ventilators plus anesthesia equipment — a representative OEM customer for medical-grade flow and capnography sensors and a downstream channel for Sendsor's products.
• ICU Medical: US-based manufacturer of infusion pumps and drug-delivery systems — a representative OEM customer for Sendsor's Microflow sensor and a comparable end-market participant in drug-delivery devices.
• Hamilton Medical: Swiss ventilator manufacturer with high-end ICU and transport ventilation products — a representative OEM customer and downstream channel for hot-wire flow and CO₂ sensors.
• PARI: Established German specialist in inhalative respiratory therapy and spirometry — already a strategic Sendsor partner (Lufttacho) and a representative customer/peer in pediatric and home-care respiratory devices.

Direct peers

• Sensirion: Swiss manufacturer of high-precision flow, gas, and differential-pressure sensors used in medical ventilation, spirometry, and E-Health devices. Closest direct competitor to Sendsor's hot-wire medical flow sensors, with overlapping OEM customers in respiratory care.

Regional players

• Drägerwerk: Germany-based medical technology company focused on ventilation, anesthesia, and gas detection — both a potential OEM customer for Sendsor's F30 and CO₂ sensors and a vertically integrated peer with its own sensor sourcing in respiratory care.

Broad incumbents

• Philips Respironics: Broad incumbent in respiratory care (ventilation, sleep apnea, home care) — a potential OEM customer and a comparable channel into the same home-care and hospital ventilation segments Sendsor targets.
• TE Connectivity: Diversified sensor and connector manufacturer (including the former First Sensor business) supplying medical-grade flow and gas sensors to ventilator and respiratory OEMs. Comparable in end-market but with vastly greater scale and global footprint.
• Honeywell International: Global industrial conglomerate with a large sensing portfolio including gas flow, pressure, and medical gas sensors used in ventilators and anesthesia equipment. Represents the incumbent scale competitor Sendsor must displace for OEM design-wins.
• ams OSRAM: European sensor and photonics leader with medical-grade flow and gas-sensing products targeting respiratory and patient-monitoring applications. Comparable as a broad incumbent pursuing the same medical OEM channel.
