Biosilver

What Biosilver does

Biosilver (株式会社バイオシルバー) is a Yokohama-headquartered Japanese company that develops, manufactures, and sells non-contact bio-sensing monitoring systems primarily for the elderly care market, with adjacent offerings in childcare and rehabilitation. Founded in 2010 and incorporated in 2011, the company employs 71 people and operates six regional sales offices across Japan (Sapporo, Sendai, Yokohama, Nagoya, Osaka, Hakata) plus logistics and repair centers. Its core technology is a proprietary non-contact sensor mat placed under the mattress that detects heartbeat, respiration, body movement, sleep state, and bed-exit events without physical contact or restraint, protected by patents and manufactured in-house. The product portfolio is anchored by the aams monitoring robot family (aams standard, aams+ with AI-powered fall risk classification, and aams call wireless call system) and extends to bio next bed-exit sensors, bio call kai wireless nurse call systems, a broad line of wired and wireless floor/bed/chair sensors, the smile baby infant monitoring robot, and the mairiha rehabilitation device; Biosilver also distributed third-party products including aba's Helppad2 excretion sensor (primary distributor contract ending June 30, 2026).

Biosilver makes money primarily through hardware sales to nursing care and welfare facilities under a quote-based direct sales model, supplemented by dealer/reseller channels, OEM/ODM contract development, and Japan's long-term care insurance (介護保険) rental program for eligible products. The company holds medical device manufacturing/marketing and manufacturing licenses (14B3X10032 and 14BZ200345), and has been validated by government programs including a 2014 METI robot care machine demonstration deploying 1,222 units across 91 facilities, the 2020 Kawasaki Standard (KIS) certification, and the 2025 Osaka-Kansai Expo Osaka Healthcare Pavilion. Strategic system-integration partnerships with France Bed (M-2), GoodTree (Care-tree), aba (Helppad2), and CARE CONNEXT JAPAN (CARE KARTE) have built an ecosystem in which aams increasingly serves as the unified care-data hub for nursing facilities. Recent additions include AI-driven fall risk classification via Rehabilitation3.0 (October 2025) and ongoing joint research with Yamagata University and Kinki University on sleep monitoring.

Revenue model

1. Welfare equipment manufacturing and sales: Biosilver develops, manufactures, and sells its own proprietary sensor-based monitoring systems (aams, aams+, bio-next, bio-call kai, floor sensors, etc.) primarily to nursing care facilities, elderly care homes, hospitals, and childcare facilities. Revenue is generated through product sales, with some products eligible for Japan's long-term care insurance (介護保険) rental program.
2. Third-party product sales (Helppad2): Biosilver previously acted as the primary distributor for aba's Helppad2 excretion sensor (総代理店), selling it as a handled product. As of June 2026, this partnership transitioned from primary distributor to regular sales dealer following contract termination.
3. OEM/ODM contract development: Biosilver accepts OEM and ODM product development projects, combining customer technology with Biosilver's sensor technology. They offer small-lot production, accommodate cost requirements, and provide one-stop service from proposal through development, quality control, manufacturing, and after-sales support. Development policy emphasizes speed as a manufacturing company.
4. Medical device manufacturing and sales: Development, manufacturing, and sales of medical devices under medical device manufacturing/marketing license (許可番号 14B3X10032). The company holds manufacturing permit (許可番号 14BZ200345).

Core offering

Biosilver manufactures and sells proprietary non-contact biosignal sensor systems for the Japanese care market. Its core aams product line uses bio-sync sensor mats placed under mattresses to monitor heart rate, breathing, body movement, bed exit, and sleep state in real time, and is sold primarily to nursing care facilities, elderly care homes, hospitals, and childcare centers. The company also produces supporting wireless nurse call systems, floor and bed sensors, an AI-enhanced aams+ model, and infant monitoring (smile baby), with related OEM/ODM contract development services.

Product overview

Biosilver develops, manufactures, and sells a comprehensive elderly and infant monitoring system portfolio centered on its proprietary non-contact bio sync sensor technology. The core flagship product is the aams (アアムス) monitoring robot family — aams (standard), aams＋ (AI-enhanced with fall risk classification and FIM estimation), and aams call (wireless call system) — which use sensor mats placed under the mattress to monitor heart rate, breathing, body movement, and sleep without physical contact. Supporting the aams ecosystem are bio next (biometric bed-exit sensor), bio call kai/bio call kai II (wireless nurse call systems), and a full line of wired and wireless sensors (floor sensors, bed sensors, chair sensors, bedside sensors, side-rail sensors, biosonic ultrasonic sensor). The portfolio also includes smile baby (infant monitoring robot) and distributed products Helppad2 (excretion sensor) and まいリハ (rehabilitation device). Products interconnect via nurse call integration, network cameras, intercoms, and care record software.

Scale indicators7 records

Recent moves8 records

Expansion highlights6 records

Broad incumbents

• Stanley Healthcare (Securitas Healthcare): Large US/global incumbent in senior living safety and monitoring including fall management and wandering detection. Overlaps in elderly monitoring use cases but at much broader scale and with different technology emphasis.
• Paramount Bed Holdings: Japan's largest specialized bed manufacturer for medical and care settings, with growing activity in sensor-integrated smart beds. Overlaps with aams in the Japanese nursing home market and bundles monitoring with its dominant bed position.
• France Bed: Major Japanese bed manufacturer and existing Biosilver integration partner (M-2 system). Serves the same nursing care customer base and competes with broader care facility solutions, making it both a partner and adjacent competitor.
• SoftBank Robotics: Japan-headquartered developer of care-support robots (Pepper, Whiz) and broader AI/sensor solutions targeting nursing care facilities. Competes for the same Japanese care-tech wallet and government demonstration budgets.

Emerging players

• CarePredict: US-based AI-driven elderly health monitoring using wearable and ambient sensors to predict health deterioration. Comparable in layering AI analytics on top of sensor data for proactive risk identification in senior care.
• Essence SmartCare: Israel-based provider of remote care solutions including bed-exit and fall sensors integrated with monitoring platforms. Similar product architecture (sensor + cloud + alerts) targeting the elderly care market.

Direct peers

• Tunstall Healthcare: UK-based global provider of telecare and remote patient monitoring including bed sensors and personal alarm systems for elderly care. Closest large-scale international peer in the integrated sensor-plus-nurse-call elderly monitoring category.
• EarlySense: Israel/US-based pioneer of contact-free vital sign monitoring sensors placed under the mattress — direct technological parallel to aams, serving hospitals and post-acute care. Closest functional peer in the bed-based biosensor category globally.
• Carecom: Japanese care facility software and monitoring provider with "Life Sensor" bed-exit detection products competing head-to-head with aams in the same Japanese nursing home market. Direct domestic competitor with similar GTM to nursing care facilities.
• aba (Helppad): Japanese developer of the Helppad2 odor-based excretion sensor — formerly distributed exclusively by Biosilver. Now a former partner competing as both technology supplier and potentially as a self-distributed or alternative-channel product in the same Japanese care market.
